I don't mean to offend anyone, but the only thing I have seen from this topic is opinion without value added. If I were trying to decide which coating to use, I'd probably want to get my hands on some data... or at least some data sheets to compare if I really wanted to help.
If you really want to help the original poster, then post the datasheet from the coating that you used and let him seek test data from the manufacturer. Your opinion on how you applied it and the mistakes that should be avoided is very valuable to the original poster, not your "low sample size" opinion of how the coating performed over a relatively short period of time.
It also depends on what kind of paint is being referenced. If you reference rattle can paint (enamels mostly), that's not a fair comparison because enamels are pretty poor compared to professional coatings. Urethanes are far more durable than enamels and there are industrial coatings that perform very well for certain applications (like this).
So, would someone please post some powdercoating data sheets or data. I can post some industrial coating data.
