Bro, sorry that no one has a clue .
It sucks! Let's look at possibilities though .
Createx is heat cured , maybe it wasn't fully cured and once a wet coat of clear was put down the solvent penetrated through and discolored it.
Maybe it blushed and is better now that it's dry?
Hopefully others will be cautioned with this paint and wet coats of varnish .
Me?, I use automotive base Coat clearcoat, it has its quirks too , but predictable .
Hope it's gotten better since it dried , if not maybe a hair dryer and heat the area to force any moisture out .
Might be the culprit .
