Based only on my experience and nothing else, I've found that epoxy paints which are not 2-part to begin with (requiring measuring and mixing prior to application) not not any better than standard enamel paint.
What I can tell you is that if you plan of doing clear coat, which you should, buy your paint as a complete solution. Don't buy one brand of paint and then go buy clear coat. Buy primer, paint and clear coat at the same time and check for solvent compatibility between them all before buying any one. Sometimes a person will buy and apply paint only to find that there is no clear coat that is compatible with it. Rustoleum used special solvents (which make it smell great, I'll add) but being non-standard you may have trouble finding a good clear coat to use with it.
