Bassbull,
Powder paint's durability is achieved by heat curing. If you just paint the jig and drop it on a concrete floor from about waist high it will chip. At that point it is brittle like glass. After heat curing it is far stronger. If dropped it, it will bend with the lead, so if the jig dents you will see the dent in the paint. I always heat cure all my powder painted items and unless you are adding eyes or some other stick-on you don't have to clear coat it.
