getting ready to paint

[82chevy]

well after some posts here i decided to do some work on my truck. i replaced the floors,inner fenders,fenders,cab corners, inner/outer rockers and the doors. after that i used body filler on some spots and primmed everything with nason fullfill acrylic primmer. i have about 4 coats on it and have sanded it with 220 between coats. im about to sand it down with 320 and then spray on my color coat on. do i need to spray on a sealer or a different type of primmer before i can paint it? also is there any other steps that i need to do before i can paint. if you havent noticed this is my first time doing body work. also im using a devilbliss starting line gun. and advice you can give me will be greatly appreciated.

You say you used an acrylic primer? Was it a two part or just reduce with lacquer thinner? If its not a two part primer you might notice after the paint has been on for a few months it will pull scratches from your body work. You might want to consider some sort of barrier sealer and then several coats of a urethane two or three part primer.

I agree - use a sealer.  I use epoxy pimer as my sealer, just reduced.  If not you have a chance the color coat solvents will weaken the bond of the base material.

yea i went ahead and sprayed a sealer on it. the primer was reduced by low voc thinner. the sealers moisture resistant right? so would it be okay to park it outside in decent weather for a day, maybe 2 tops? but it will be in the 30's. also i sprayed the primer and sealer with the devilbiss starting line gun. i think it came out great but this is my first time painting. will this put down color just as nice? i believe its either a 1.3 or a 1.5 tip. it also have a 1.8 that i used for the primer. im just spraying a single stage arctic white. i scuffed the sealer with 400 grit paper. is that going to be okay? Blazin, u mentioned i should spray on more primer? both the primer and sealer are made by nason. im not expecting a show quality paint job since this is going to be my dd but i still want it to look good. JJSZABO, after i saw your post of your project it gave me the confidence to start on my truck haha. and btw hows that coming along?

I only mention urethane primer because it is about 500 times better than acrylic primer. It fills better, it dosn't pull scratches, and being urethane based it can be painted right over without any sealer.

well since i already put on a few coats of primer and then sealed it ill probably just paint it now. or should i shoot on some urethane primer and then paint it? another words would it make a difference at this point since its already sealed

I'm still working on it.  Painting it piece by piece.  Have you seen the cab painted?  The cab in on, the inner and outer fenders are painted but not on.  I am waiting to finish the doors before I install the fenders.  The fenders need to be lined up with the doors first.  

Blazin is the MASTER when it comes to body and paint work.  I've learned alot from him.   If you can, heed his advice.  Single stage paint is good for a daily driver.  I am using SPI products with color and clear.  When I get around to doing another vehicle, I think I am going to use single stage followed by clear.  Alot of people are going that route.

If its already sealed I would go with it. Especially with single stage.
