I am surprised I don't hear too many PNW folks talking about Softex. It has a number of applications including coating jig heads. I give my powder coated jigs heads a coat or two of it, which takes all of about two seconds apiece, and they are are virtually chip proof. My one complaint is that when used with powder coat is that it (softex) tends to dull the shine a little, but a small price to pay for lasting paint.

Works well to protect painted beads also and the flat look is actually a bit of a bonus in that application.
