Is this normal wear & tear or a problem ?

pearl's and metalic's don't like anything that is layed on top of them when they are made of enamels and or laquer's..rusto.= enamel///krylon=laquer.

metalic's/pearl's LAY on the primer or color coat below them,never really bond together...easy peel.

enamel's and laquer don't like each other unless sprayed on together wet.

gloss paint's do work well only if scuffed really well after it's had ample time to cure..

try to stick with the same brand paint's all through the different steps.

sounds like your mixing 5 different liquids/brands to get to the finished product.2 or 3 of these are fighting each other not allowing the other's to bond or get a grip as they say.
