Turbo primer as a sealer?

T

Tinman

Not for resto, for collision type work. Anyone use turbo primer reduced for a sealer.
I love epoxy,but for production/collision thinking maybe this would be the ticket
Was going to get the 2k sealer,but wondered how turbo reduced would fair?
Be nice to have the turbo for filler primer on repairs and only have 1 product on the shelf,if it works reduced as a sealer also.
If it will work, what is the time frame for applying basecoat?
 
you would be better off just switching to the sealer for your primer and sealer steps. the sealer is a 2k primer as well and fast too. it builds really well. its been some years now but when i used to use the turbo primer i tried it for sealer a few times and always got some dulling of the clear when i did it.
 
Was the clear dulling when using turbo wet on wet? I generally don't do wet on wet.
The turbo would be air dry and usually lightly nibbed (and or scuffed ) before base, even when reduced as a sealer.
Or is this a problem with using turbo as a sealer in general ?
How does the 2k sealer compare to the regular 2k primer for repair?
 
Wow, can't believe more people haven't thought about using turbo this way. Thought there would be alot more feedback.
 
no thats for wet on wet which is what imo a sealer is. if your going to let it cure out then your just reprimering the car and there is certainly no problem with that. i personally use the 2k sealer here in the shop. the difference is the fillers in it seem to be ground finer and its sprays wetter, smoother and more slick. basically mixed at 4:1:2 its texture free. one coat can be denibbed in 5-10 min then base can go right over it with no problems. as for build, its about the same as the regular build primer. the regular build always seemed to spray real grainy and dry to me. i find the 2k sealer much nicer as a primer.

It may be that a lot of people think it would be ok, but the end result isn't as good as using a sealer, and they just don't want to say it because you CAN use it direct to paint, but the question might be, would it be better not to...Dave
 
in 40 years of painting i have never even thought of using primer as a sealer nor will i .

Is the 2k sealer all you use for your higher fill apps , or do you recommend turbo or high build? Will be ordering a gallon each black & white 2k sealer for my production and collision purposes, and stick with epoxy for restro ,custom stuff where I have the time to let the epoxy(as a sealer) sit if it needs to be denibbed or trash sanded out. I've been using the spi reg. 2k as my filler primer , but have the same issue as you with the grainy deal. Good product for the money ,but would switch to turbo or high build if there are better. I really like the Sherwin Williams. P30s for my 2k surfacer/sealer , but they're pricing me out of using them for anything but new or high dollar work. In which case the spi epoxy comes back into play for my sealer.

Don't need to let the reduced sealer sit much after spraying....we treat it kind of like the first coat of base....spray the sealer, clean the equipment and by then you're ready to spray base...
 
i stopped using the regular build years ago because of the grittiness. the high build sprays much nicer. if i need real high build then i do use the hb primer. i have used the 2k sealer before as a real high build primer. you can do that. unreduced its pretty think stuff but i just find the hb primer to be a little faster when built up thick.

Using a urethane primer over reduced as a sealer has been a common procedure for many years, epoxy is always better IMO and I think some of the fast cure high build primers aren't designed to be used this way. Epoxy works best IMO but when I did collision work all we used was a dedicated urethane sealer or an over reduced regular urethane primer.

You are referring to 2k sealer correct , not the reduced epoxy? Would ideally like to only use epoxy reduced for all my sealing purposes. But in everyday production/collision jobs more often than not , I find the need to denibb trash or imperfections out. This is where the 2k sealer(ability to sand in 10 minutes) would be a big time saver over epoxy.

Is there a reason you don't use turbo vs the high build? I've only used the reg 2k , not sure how the other 2 compare against one another.
 
the whole point of sealer is to create a solvent barrier . i just dont see urethane primer doing that. to each his own i guess.

I agree. But most of what I'll be using the 2k sealer for is sealing new replacement parts or used parts that just need to be scuffed & sealed on everyday collision work. For jobs with major bodywork(filler,surfacer,ect..) and especially resto,custom,highend stuff, I will 99.9% of the time use the epoxy for my sealer as well as the foundation.
 
with epoxy as a sealer, if you spray thin and mix 1:1:1 and limit to 1 coat then as soon as it flashes and you clean the gun you can go right to base.

i did used to use the turbo. its been a long time. i think i switched to the hb simply for build and the 2k sealer as a primer because it was an all in 1 deal. it had the build of the turbo but i didnt have to stock a sealer and a primer. i never noticed a difference in cure speed between anything spi had that was turbo compared to the rest of their stuff. for me anything called turbo or speed or production give me a knot in my stomach. i know these types of products have come a long way over the years and i shouldnt feel that way, but.....

for shine's comment, he is right i guess but depends on what each person is looking for. for me, in a sealer i am looking improve adhesion of the base more than anything and make a more even surface for the base to lay on. im less concerned with a solvent barrier i guess because my stuff sits in base so long before it gets cleared.
 
I haven't tried the sealer as a primer yet, but wouldn't the finer cut also offer more shrink resistance because of the finer cut as well??
 
hmmm no idea. i havent noticed it shrink any more or less than any other high quality urethane primer. i can tell you the stuff is really close to house of kolor's koseal which is their urethane primer/sealer......if you have ever tried that.
 
chad I use the sealer as a primer as it winds up real tight.much tighter than the reg. primer.so whats it like havin a boss now lmao,cousin russ
 
May have to try it one of these days.. Boss is fine, were locked on different sides of the wall.. lol.
