Solvent Pop as I understand it, is improper 'curing' time between coats of paint. The solvents are forced to escape through the next layor causing tiny holes in the final coat.
That is one reason for chosing the correct hardener based on expected temperature during the painting process.

Solvent pop can come from a previous paint job. In many cases the solvent pop will not become visable until the clear coat is applied and by then it is too late. It is caused usually through too heavy a coat of material or improper flash time between coats. In some cases with catalized primers, if the primer is heated between coats to dry it faster solvent pop will occur. I encounter these problems from time to time in my work and it can be a frustrating problem at times. Sometimes the pop can be buried under a heavier coat of clear or primer. If this doesn't work a skin coat of finish plastic can be applied over the surface after it is sanded and then primed and repainted. Your best method of repair is to strip the finish and start over, although this may be impracticle and not an option in your case.
