When powder paint is properly applied and cured, it's just as durable as vinyl, if not more so. If your powder coated jigs are chipping easily, you're doing it wrong. It also doesn't subject you to toxic fumes and the drying time is not affected by humidity. I only use vinyl for painting eyes.

It's important to follow the curing instructions from the manufacturer. Different colors have different curing times and temperatures.

One you get the knack for how long to hold the jig over the heat source before dipping it in the power, you won't get drips.
