Where To Buy Gun & What Else Do I Need???

Shine's method is to have enough base mixed up to do the whole car (usually at least a gallon) and once it is thoroughly stirred (not just shaken), split the batch into quarts. Home Depot and lots of other places sell empty quart paint cans for around $3 each. This is a great idea, especially if you have a quart left over -- never know when you'll need a perfect match for a repair.

That is a great idea! I wonder if the colours place would do that for me? since they have to mix it all up anyway right?

Any idea how long the base will stay good if in a sealed container?

I remember DUB saying one time you can use that left over paint...not to do a complete repair job... but at least the final coat or two to help your blend look like new vs. trying to match it 100%
 
I guess its too late on the gun, but I was going to recommend just buying it at your local paint supplier even if it does cost you a few extra bucks. All of the places I go to have atleast a couple of guys who spray on a regular basis.. You tell em what you want to do and they will help you pick something out. Just like Chevy vs Ford, everyone has their preferences. But atleast my local supplier balances personal preference, customer experience, etc. Anyone who is pitching a 800$ gun to a first timer is just looking to make money. A first timer will spray just almost as good or bad with a clean fresh gun from Harbor Freight in the 50 dollar range as they will with a lower price point pro gun(3-450).. Difference between the HF gun and a pro gun is the the beginner will soon find value in a nice gun.. However it will take years and years to get to where you will see the benefits of going from a 400$ gun to a 900$ gun....

On a DA, I have a Hutchins 3500.

They run about 300$. I got it in a bulk trade about 13 years ago. At the time I would have never paid that much for a DA... After owning it, if it died tomorrow I wouldn't even look at anything else, I would buy another in a heartbeat.. Ergonomics are a 10.. It is light weight and perfectly balanced. It is counterweighted so when it runs you get absolutley no vibrations.. I have used it for hours and hours at a time and didnt feel beat up. A freind of mine who is notoriously cheap has a REAL DA(most modern sanders we call DA's are really orbitals) he got at a yard sale he bought for 5 bucks... But he always hand sands everything(and the job usually turns out like crap because he runs out of energy) and I keep asking why he doesn't use a DA.. He said he didnt see the value in it.. So one day I took the Hutchins over and he's buying one

I run an Ingersoll type 30 with a true 5 HP motor and its at its tipping point, I have a second one running in tandem that does kick in now and again during long sprays.

Holy smokes! How many people you have running in your shop at the same time?? I have either a T30(maybe a T20 if there is such a thing).. All I know is its big and heavy for a 80 gal, rated at 5hp, big twin piston compressor head with big coiled copper lines between the head and tank to make a lousy cooler, and has to be fired off this fancy GE breaker box/contactor setup. Mine kicks on about 120 psi and off at 150 or 160?

Thing is, I can't think of a tool that runs long enough that the compressor can't actually work through to a point of shutting back off in less than a minute, and then cycle back on several minutes later. The worst would be the DA and the airfile, but the compressor exceeds their usage needs.

If you had a Home Depot or Harbor Freight special, I wouldn't be suprised. But I am suprised with you having a real IR.

How much universal clear will it take to do a corvette and the engine bay? I guess I can buy just enough to do the engine bay for now as clear for the other areas is a while away.

Get 2 gallons(1 gal of clear and the 1 gal of activators). It should be more than enough, depending on how many things have to be redone.

Base question: If I go to colours(only place local) and get some PPG paint mixed up. I saw you should mix ALL the paint for a metallic job at once.
How long will it last if I use only a little on the engine bay and need the rest for next spring or late winter? OR. should I just get a little for the engine bay... then when i'm ready get some for the car?

Dont worry about shelf life. I have base coat that's from the 90s. it holds up remarkably well. Also keep in mind that by the time you buy 2.5 qts it almost costs as much as a gallon. So just go and buy the gallon.

That is a good idea... However I take a slightly different approach.
After buying several gallons of base, and you guys know how its filled ALL the way to the top like 1/16" from the lid, I got frustrated spilling the first pint on the bench trying to get it into the first quart mix cup. At $500/gallon thats what $50 bux wasted?
One day while buying base, I asked the guy at the paint store, "Ok, how do YOU keep from slopping the first couple of pours out of these super full cans??" His response? "Good aim and fast"...
Screw that.
After one more time of making a mess, I started buying my gallons but telling them to give it to me in two danged cans! IE, I get two gallon cans that are only half full. They don't charge me extra. With the can only half full I can pour out of a gallon can into a 8oz mix cup without making a mess, after a few Bud Lights.. If you are worried about slight color differences just pour them between the two cans...


I agree with bo, that you're ambitious to be determined to pull off a metallic as your first job, but it can be done. I painted a couple cars in the 90s, and a fender here and there prior to 2012. In summer '12 I did my first all over in ages. It came out ok... It gets compliments but I am not happy with it.. Lots of dry spots, some orange peel. Thats a long story.. i learned alot about my particular shop on that job too.. One of them don't spray at sundown with the evening sun coming straight in the door.
But a few months later I had to do a car for a relative. A silver metallic.. That car came out AWESOME.

Tips:
Use GOOD basecoat... If your dealer is PPG, do NOT use Shopline(or Omni depending on their standing with PPG). Use DBC. Coverage is better on DBC which is important on a metallic, the micas they use in DBC is better, and the color match is better. Figure about $500(+-100) for a gallon of base...

Prime or seal the entire vehicle in the same color, so before you paint its one certain color(probably grey or black for that color, likely black). But if you have different color primers at the time of spraying, or you have areas with no primer you can get color differences that show up in the sun.

Finally.. Heres the big thing for doing a metallic.. Do 2-3 coats(probably 3) to get the coverage. Once you have what looks like good coverage, open your fan up as far as it will go and back the gun away from the car like 16". Go over the entire car in a totally random pattern. Figure 8's combined with waving your arms around. This will eliminate the tiger stripes that Bo is referring to. 10 years ago I sprayed my bass boat viper blue as if it was a solid and once it was clear you could see each pass of the gun. It looked like the lawn after I cut it, or the floor after running the vacuum. Thats what tiger stripes are. If you don't do the final step of that random coat, you will have them.
Then before you clear, tack rag the entire car as soon as the paint flashes(dry to the touch). In general, the metallics some of them will stand up, but the last step of opening up the fan and randomly fogging the car leaves alot of particles on the car that land dry.
 
2 guys when running sanders, grinders, etc. My main tank cuts in at about 150 and out around 185 if I remember right. The second tank cuts in just above 150. The thing has no problem keeping up with air tools, they are on a line regulated down to about 45 lbs or so, and no problem with keeping up with Individual panels either, just when it gets to the big long sprays, like a truck bed in and out.... Having the extra bulk in the other tanks helps a lot as well, I'm sure it could prob keep up on its own if I let it, but I have another compressor so I go ahead and stage it in just so its a non issue.

When I started out on this "hobby" that has turned into a second job I had the biggest compressor you could buy at the big box stores, it did well, for a while..... Anyways I guess now days I'm pretty gunshy on making sure I have tons of air, I remember when I got going I had tons of problems with clears especially and just couldn't figure it out, the compressor popped about its third motor in a year or so and we bit the bullet on the t30, zero regrets, wish I'd have done it sooner. The main thing that the first setup taught me was that all that jazz on the sticker on the side is in a perfect world and at less pressure than you need, when you crank up a big box unit to get the kind of pressure you need out of them(at least in my instance) they start munching motors and getting hot, wet air pretty fast.

I'm actually planning to add another t30 over the winter just so I can cycle them in and out, and have a backup if one fails. Anywhoo I'm ranting....

And the drop coat is a big yes, that's how I was taught and it works fairly well(as long as things weren't too bad), I've read of a cou of guys having everything all ready and panel painting, assembling the next day then drop coating the beast at once, never tried it, but then again I don't move that fast anyways.....

Another possibly worthwhile idea may be to have a base mixed sans the metallic, then you could panel paint and throw a coat of intercoat on plain, then assemble, scuff and lay your metallic on top, then if there's an issue you could always sand and not be to sqaure one....
 
Thanks for the tips guys! Yeah....pretty much the more people say I "can't" do something the more I tend to want to try it lol. Plus I know I won't be happy with a basic color paint job which means I either try it myself. Or pay big money for someone else to paint it...which defeats the purpose of this car. 4yrs ago I knew nothing about cars and screwed up changing the oil on my '96 vette. Right there I decided I needed to learn so bought the '69 to teach me how...luckily(i think) it's needed just about everything lol....so I've learned a LOT.


I'll definitely practice first and we'll see what happens with the metallics. Worse case I have to sand it off and try again... which isn't desired but also isn't the end of the world.
I read somewhere for metallics try to overlap 75% instead of the usual 50% and that might help some too?

I upgraded to this over the summer... while it's not the best of the best it's going to have to be "good enough" as I'm not hauling a 2nd huge one down to the basement!!!!!
Not a bad deal for $650(reconditioned Kobalt by CH)

Don't mind the mold...I informed the owners and since I don't care...they don't care. But as you can imagine the air is moist! but so far nothing gets to my air nozzle with my hose, trap, and filter.

If you can believe I sandblasted almost everything on the car, even the frame with that little dewalt. 40psi or 1-2min at a time! HUGE mistake not upgrading sooner...but I had to prioritize.... new LS1/T56 swao...or compressor....
 
Biggest deal that has killed compressors like that campbell hausfield compressor is the check valve on the top of the tank. they corrode pretty quickly if you are using it at capacity where it is on more than it is off. Makes them harder to open and forces alot more stress on the valves and heads. They put the check valve there so the compressor can unload and start freely, but corrosion in that valve make it harder to open.

Also, if you are gonna adjust the preset pressure, the best way to set your top pressure is with an amp probe. See the amps the motor is drawing at higher pressures and make sure its not at the nameplate limit.

Only when I sandblast am I using it a lot. The rest of the time it has a pretty cushy job.

But I can buy a TON of replacement check valves for what it would have cost to get a decent Ingersoll. Even their cheapest 60g are $900+. You get into 80g or their T30 series motors and you're already $1500+ if not way more. I got the best CFM I could find for as cheap as I could find. Plus I figured it being refurbished means it got looked over twice...might be pretty good for a while? Their refurbished line are not used, broken, returned, and then fixed and sold agian. It was never used. Damaged in shipping most likely or never worked to start out with.
 
Ive got an 80 gallon IR 5hp from Tractor Supply several years ago. It has always handle everything that I do here at the house. I have noticed that it doesn't keep up with my blast cabinet as good as it once did. When I started spraying epoxy I did get those pock marks. I talked to Barry and he told me to have my air pressure at the wall set at the highest level. I never have a problem when spraying with my detail gun, just my larger guns. This does point to an air problem. The problem with my setup is the IR cut in pressure is 90-135psi. I also have a m60 located at the compressor to catch oil vapors and its max is rated 125, so at times I am pushing it there.

Next time I use the large hvlp guns Barry told me to try to up the pressure at the gun. I have been using my flg4 at 23-25 psi. I'm going to try it at around 30 to see how it does. I sure hope this solves my problem. The wife will freak out if I tell her I'm buying a new BIGGER compressor.
 
Where do you guys buy your sanding supplies and how much will I need for the very min. this car?
I'm an Amazon fan but that's just because they're easy to deal with...they might not be the best for all of my sanding needs I guess.


I have rolls of the 2 3/4 PSA in the low grits for my blocks. 80, 120, 180, 220. So I need what other grits?

I see 3M sells those same rolls all the way up to 500. But with a metallic I need to sand to 600 i've been told a few times. Do they not sell 600 in long rolls for durablocks?


also what 6" discs do I need for my new Dynabrade? I just got 80 for rough sanding fiberglass for now. But when I'm using it on clearcoats i'm 1000grit + right? How many and what grits will be needed you think? I know that's far away but just curious.
