ok gotta question...Ive sanded my factory paint with 180, then shot some epoxy primer (black) then followed by my Polyester High build primer (the gray) I dry blocked the poly prime. Do I shoot whole car in 2k primer next.....I have yet to get to the roof and trunk in Poly prime...and only have 1 quart of the 2K, how much can I spray with 1 quart of 2K i was thinking the whole pass side then the drivers side fender and door...and after I 2K it, just wet sand and it's ready for sealer right?

I used 180...ok cool, that's exactly what I was gonna do...thanks homie

what do ya'll use to clean before you prime? I bought some stuff by 3M called "Scuff It" its like a paste that you apply to a scotch brite pad and use water to go over the body then rinse off, alot better than using Wax and Grease remover since you dont' have to wipe on and wipe off...so I don't have a garage and I had to bring my car home since it's my daily, and it's suppose to rain, if I have a couple bare metal spots and they surface rust from the rain, can I just use that 3M stuff with a scotchbrite to scuff the rust off and proceed? I know exposed filler is not good to let get wet unless it's over epoxy so I'm ok there

I'd sprasy some more high build so you don't have any spots where you burnt through to the epoxy.I've had wrinkling problems sealing the body that looks like that.

i use the scuff it and scotchbrite on top of a painted car thats getting repainted,after i da. it with some 320.
and you have to wash it off afterwards so youll get teh bare matal wet and filler

i agree.....i would reprimer but add a little acetone to ur poly primer to thin it out some. this way it will lay smooth and will be eazier to sand and finish with 400-600 before sealer....good luck homie :cool:

2k is a high build primer used to level out body work by block sanding..sealer is used to seal in ur prep work before u apply ur paint............ :cool:

my epoxy and polyester primer are Kustom Shop brand from TCP global...so If I shoot the Polyester primer, and wet sand with 320, is there any point in using the 2K? or should I just skip on to sealer? yeah I only have a 1.8 tip, that's the biggest tip I have on the gun, and that Poly prime is thick, so I had to reduce it with Acetone like 20-30% which cut down the build of it. also I had a couple spots, just along the bodyline where it was flaking off :mad: but after blocking with 80, then finishing with 180 it seemed to stick everywhere else wit no problem....so

1.re-shoot with poly primer

2.wet sand with 320 (block) then 2K

3. used reduced epoxy as a sealer

I've read so many ways to do it, and it can get confusing, I had a game plan before I set out to do my car, but when in doubt, gotta ask questions. on my bumper filler peices I used epoxy, am I ok? do I do the same with these also or just 2K and seal?

could I use the 2K instead of the poly primer and just 400 that and go to sealer? I'm kinda iffy bout using that poly primer agian since I had flaking issues....I took that quart back and got a gallon, Its Nason Selective Urethane 2k Primer, I'm gonna be using Nason bc/cc, but the sealers gonna be the Kustom shop brand, yeah I hear ya bout using the same brand but I'm sure it'll work together

polyprime is more for the rough block, so if you have deep scratches, imperfections, i would use the poly primer,
if the surface has minimal work, just 2k it and wetsand it,
you can spray over the 2k, no need for sealer, but thats up to you

so I sprayed some primer today, I spot primed my bare metal areas with a coat of epoxy, let flash, then shot some polyester prime....then some bad shit happened....you know how water looks when theres oil in it? well thats how the poly was starting to do.....what could be the cause of this? I know the compressor at work has seen better days, you think junk got past the water separator?
