Why is my spray can clear coat causing epoxy problems?

[Simp]

I use a lacquer clear coat spray after everything is painted as an extra layer of protection from scratches, fingernails, etc. I'm not using Etex though.

put the epoxy on sooner.  With clear coats, the longer you wait the harder it gets.  The harder it gets the less things will stick to it.

the wrinkles happen when the primer doesn't have enough time to dry and when the epoxy takes the air away you get wrinkles. it happens to me from time to time. if you are use clear between colors try ex-tex spray epoxy. I use it over decals never had an issue with epoxy pealing..
