Epoxy will stick to createx just fine without a scratch coat (even better if the createx is heat set). The peeling problems I have seen are all related to the createx not sticking to the primer coat. I think this BIN primer that most people use is a weak link.
I think the issue here is with the shelac based primer.. if you do not sand it and wipe the dust with an UNTREATED tack cloth, that is where the adhesion issue comes in between primer and paint,, due to the gloss of the primer... I use the oil based, zinsser cover stain, no sanding and the paint sticks like super glue to a finger...

A good run is better than a bad stand!
