GO TO A HOBBY SHOP-or online at HobbyShack/HObbyLobby---------that sell remote control plane kits have a brand named RED BARON paints they are epoxy and the clear I have used many times on smithwick devil horses'
I take all the hardware off use 200 grit sandpapper to knock off the glaze then spray the lures with couple coats of RED BARON CLEAR EPOXY can spray it is quite tough and last all spring where the factory finish only last 1 or 2 trips then the wood is water logged .
It may not be as good as what of the custom guys use but it will be better than any other paint in a can for this....JMO
