happpen and how do I stop it happening.

sounds like a paint reaction ?combination of three paints,are they compatible.It may be the etch primer reacting with the powdercoat.Didnt think you
would need an etch primer onto powdercoat.Not an expert just an opinion

As above, etch primer is designed to eat into bare metal, if you put it on an existing coating it will react. powdercoat is fine as a primer, just key
it then paint over with topcoat.
