Fish eyes in primer

I know why they are there. I was having trouble with my DA not spinning freely so I put some tool oil down inside the bearing. Well I hit the tigger and accidentlysprayed some mist of the oil on front of the Tbird - primer / filler / exposed metal mix. Well I tried to clean it up the best I could and I sanded the area. Well that area is fine, but there must have been a fine mist because I've primered some other areas and I have fish eyes. Should I sand off the new primer anywhere there are fish eyes completely? then what?

I know, newb mistake. I have a new DA now.
 
If they are 1/8" or less in dia, you should be fine, any bigger i would spot sand down to metal.

LOL, I have pretty much lived by that rule, been bit once and never again.
 
well this is killing me. It's sunday afternoon, last drop of primer out of the can, full batch in the gun and I'm still getting fish eyes. Already replaced air filter / water seperatoir / hose, drained compressor, etc. Went over everything w/ waterborne, and wiped down good and still have them. Tried dfferent paper towels still have them. It was spotty at first, but the more I try to remidy them, the worse it gets. I can't figure out if the the contaminents are in the primer that's on panels or if it's in the air source. It would seem like it's in the air source, but i've never had a problem before and the compressor oil level isn't going down.

I could just keep spraying, but it's scaring the crap out of me. I still need to shoot my epoxy sealer/color and base of couse and I can't have fish eyes then.
 
Arrowhead,

I once had a shock absorber that I was working on blow oil all over my car. The car was soaked and I was really worried, as Im sure you are. I wiped it several times with waterborne using different rags. Then I blocked it and wiped it more. I couldn't believe it, I never got a single fish eye. I called Barry that day in a panic, and he quickly put my mind at ease. He was absolutely right. It has been a year now and everything is good.

My car had epoxy and Turbo on it at the time of the accident. Exposed filler could be a whole different story...Im not sure on that.
 
Not that what I do is always the right thing, but I would let the car sit, sand that area really good, degrease and try again.
 
Well I went and sprayed everything one last time, the fish eyes aren't consistant and only show up in some areas, mostly horozontal surfaces, verticle doesn't seem to have a problem. So that tells me it's airborne rather than from my air supply.

Now that I had some time to relax and think about it a little more, I'm feeling pretty stupid. The car has a transmiaaion leak and it has a pretty good sized puddle on the floor. It was only a drip, but now it's grown quite a bit. It's almost like the dust in the garage has become contaminated with the fluid as it evaporates and that is landing on the horozontal surfaces causing the fish eyes.

In my haste to keep working on the car I neglected the one basic rule of cleanliness.

I put speedy dry on the puddle and a can under the trans to catch the fluid. Now the trick is to get the garage as clean as possible and air it out.

It could even be somebody upwind spraying their tires with that tire shine crap. It could be a hundred different things! We all get bit sooner or later. The last time it happened to me it was from a damaged A/C line spraying refrigerant and PAG oil all over the place. Had to replace the booth filters before the problem went away!

I hope you figure it out.
 
I don't think an oil puddle under the car would cause the problem unless somehow it got into the air flow but how? sounds like you'll need to clean it up to rule it out. Where are you pulling your intake air from? Heat source-oil? If it was airline or compressor problems it would be on all of the panels.

I've been there, it sucks for sure. I had a three week ordeal in one of the collision shops I worked at years ago-everything I painted that was horizontal had fisheyes and I was pulling my hair out trying to figure out what the cause was. Never had problems like it before and I looked at everything in the shop as a possible cause including a few of my coworkers-I've seen sabatage happen in a few shops. Then I figured it out.... I had switched brands of underarm deoderant and very very small dustlike particles were coming out of my shirtsleeve as I painted hoods,roofs, decklids. We didn't wear paintsuits much back then. It was troublesome untill the problem was figured out, I was washing my clothes without fabric softener and trying a lot of different things before I figured it out.
 
I had another thought on this today. I know it is cold here....could your furnace be the problem? You probably thought of this already, but just incase.;)
 
I haven't totally figured out where the fisheyes came from originally, but what ever it is, it's in the primer and keeps making new ones. I sprayed a reduced coat of high build and I sanded 320 and then 600 wet. All the panels look real good now, but you can ssee tiny light spots in the primer in some areas. If I spray some waterborne W&G remover on the area I can see little craters start to form. The only thing I can think of at this point is to go over every square inch and sand out every little spec.
 
Did a little surfing and found this gem from Barry from '04:

"Use NO!!! lacquer thinner! It will smear the friction modifiers (depending on brand and type) in the trans fluid and you will have a mess.

Take rubbing alcohol 50%
Tap Water 50%
Now add 10% ammonia.
wash twice and dry with clean rag each time.

Let dry about 10 minutes and hand scuff with 320 and apply one
coat of primer over just to make sure you got it all out. If primer
goes on smooth you've got it whipped!

Another issue I just thought of, Did this happen in a closed up garage? If outside no problem in a small garage trans fluid is the worse fish-eye causer of anything, you may need to wash the whole car with the above mix if it was. Make sure you use and keep the rags clean while cleaning maybe get a roll of heavy duty paper towels.
Also all trans fluid on the floor must be delt with before anything is done."

Arrowhead, I hope you don't mind but I copied your post over to the Tech Tip "Fixing Fish-eyes" thread.
 
I tried the alcohol and water trick. It helped a lot, but there were a few stragalers after rubbing down real good twice on a test area. If I spray water over it I can still see a few here and there form. I'll try to find some ammonia and juice up the mixture a little.
 
I'm not getting anywhere here. I cleaned w/ the mixture mentioned above and no luck. It doesn't bead up water, but when I did a test area w/ epoxy they came back. I sprayed a test area of epoxy mixed as sealer and it's worse. Not sure what I'm going to have to do to remedy this. Sand all the primer off?

On the other hand, the craters in the epoxy are not down to the substrate and when it dries, they are not too noticable. Maybe apply a second coat of epoxy and them wet sand with 600? As long as I don't break through to the 2K underneath it will be sealed up? Just a thought.
