A question for my good friend who is doing a 64 Olds F85 (More power to him, huge body!!!) Anyhow, he has done the whole body with Evercoat primer...Im not personally familiar, but its a high build primer, and the supply shop he bought it from told him to reduce it with lacquer...They also sold him the base coat and clear he will be using, so I doubt they would have screwed him up. Today he was talking to a guy at a body shop (maybe a mistake) who said the lacquer might give him a problem when he does his base coat. (I cant figure why) He suggested spraying the whole car with an epoxy primer before the base coat is applied. And he told him not to sand it (the epoxy) I dont think thats right either, and I dont believe he needs the epoxy. I thought the evercoat primer was meant to spray right over? So now my friend is worried that something might go wrong...what do you guys think??? I have to get my buddy to join here, I told him he's missing out on a whole lot. Thanks very much. My paint job is coming along fine so far by the way, thanks in part to you all. John

MARTINSR might back me up on this, but if it is true he needs the laquer in the primer, it is essential that he let the primer cure long enough to get the solvent out of the primer before he shoots a base coat. If he doesn't, it will look good this year and next year peel off in sheets.
I would give the primer at least 24 hrs before shooting a polyurethane over it.

Johnny, you didn't say what kind of primer it is. The fact that someone told him to put lacquer (thinner?) in it doesn't mean much. You could replace the acetone in polyester primer with lacquer thinner. Or in some epoxies you add lacquer thinner. Now, I assume it is lacquer primer, but to be sure I would need to know exactly what Evercoat primer it is.
If it is lacquer primer, then it needs a sealer over it before the basecoat. Urethane would be the most likely choice. Not because there would be a reaction or something but because it is soluable and the solvents from the base/clear will soften the lacquer primer and cause shrinking.

If it is a polester or epoxy, no sealer would be needed.

Oh yeah, on your F-85 comments about it being a "huge car". It is the EXACT same size as a Chevelle. Out side of possibly an inch or so overhang past the frame or something.
They are both "A" bodies and share the same frame, complete floor including firewall, door hinges and latches, all windows and window moldings, etc. In fact, you could bolt the complete sheet metal or a door off that f-85 on a Chevelle. The body lines wouldn't line up, but the mounting is the same.
