I find epoxy based powder coating to last significantly longer than polyester. The good stuff from Pro Tec is worth the money. Extra seal is nice but my jigs usually won`t get old enough to lose their paint. When I went to business I tried epoxy and reached a near-indestructable level but I found it too much effort for commercial application. That being said, If you´re the kind of guy that spends 20min on an extra nice jig for an environment that won`t snag too much- why not?
Proper cleaning in alcohol helps, too, unless you wear gloves. You don´t want any fat on the surfaces, not even fingerprints.
