Epoxy primer

Since my post has been resurrected here is an update. I have been priming as work progresses and using PPG CRE epoxy. Weeks and even months later it sands beautifully. Sprays nice with a 1.7 tip and is very thick. I plan on using CRE for hi build as well for final blocking.
Reasonably priced and allows the use of one primer product start to finish!

Can you build CRE up like a high build primer? If not I would think it won't be useful for blocking unless your car is very straight. I just bought a good epoxy primer and then run of the mill high build to go over top. Most of it gets sanded off and then it gets sealed anyway.
