I haven't but some guys here use Dick Nite's Fishermun's Lure-Coat and swear by the clear top coat S-81 to protect.
You could probably paint with acrylics or any water base paint and top coat with Dick Nite's clear.
S-81 is a laquer based paint so use safety precautions and use with adequate ventillation.
