I've been looking for the best, not-outrageously-priced primer. So far, I've tried a more expensive Krylon and Valspar primers, but with both, I've had the base coat rub off on raised areas while handling the model in the course of painting it. So far, I've had better luck just layering on a couple of coats of a Citadel base straight on the plastic. The librarian I'm working on now just won't hold paint with the Valspar primer and it's going to get a SuperClean bath overnight to get that mess off.

I saw some of you mention Dupli-Color, but where can I find it? I'm guessing this is what I want to look for? I've had good luck with not losing details with what I've tried so far, but that is a concern I have, especially for this librarian.
