Question about paint & primer compatability

[sdberman]

OK....I may have made my first mistake in my Fenderbird build and need some advice.

I stripped my Epiphone T-Bird body down to the bare wood and sanded it smooth. I then used grain filler, sanded that smooth and then sprayed with nitrocellulose sand & sealer. So far so good.

I've been debating between using ReRanch Fender color aerosol spray (nitrocellulose) and Duplicolor (acrylic lacquer, I believe). I figured I'd go with Duplicolor because of the larger selection of colors.

In the meantime, I primed the body with Kilz aerosol spray primer (white). Then I started hearing about possible compatability issues between the paints and the primer. The guys at Stewart MacDonald say that I can't use the nitrocellulose paint over the Kilz. They also say that I can't use the nitrocellulose clear lacquer over the Duplicolor. Basically, they say that nitrocellulose should only be applied over nitrocellulose.

So, my questions: what compatability issues do i have? Should I sand down to the wood again and just use sand & sealer as my primer? Can I use nitrocellulose primer over the Duplicolor? Should I stick exclusively with nitrocellulose sand & sealer, base color and clear coat? Your suggestions and advice are appreciated!

Firstly, the Stew Mac guys are correct on all accounts, this is a primary thought when finishing. Nitro is better off with Nitro, but can be used over poly, but not the opposite. The Duplicolor is Acrylic "Enamel" not lacquer, thus completely non compatible with lacquer sprayed on top(It will wrinkle) Kilz is also an enamel/latex, and not compatible. If going nitro, just use the sealer as your primer, this is it's purpose, to seal and prime(sanding is the priming, giving the sealer teeth to hold the finish). If using Duplicolor, use all duplicolor/krylon/rustoleum type products.
