Richie don't waste your time. It doesn't work. Better yet go buy some and tell me how to make it work

It's a poly that doesnt withstand water very well. It really stinks in all honesty. Their paint works good but if you dip a lure in it and let it dry for even 3-4 weeks it will turn milky colored when water gets to it. If left in water it gets gooey. BAD JOOJOO. VERY bad jujoo. Total paint failure right to the bottom coat at that point.
Any lacquer sanding sealer is probably one of the best things you could use to seal, paint with createx let dry and use either two coats of thinned KBS diamond finish or a thinned light coat of Devcon two ton epoxy in no less than 30 minute formula. User use caution. All have safety precautions to take and observe. Use it outside or in your garage away from sources for ignition. Read the can. Most states now you can't buy gallons of the good things anymore. So buy 4 quarts and pay 5x more. Stupid lawmakers.
I myself try and stay away from recommending stuff and tell people that up front. If whatever you do doesn't work then your unhappy with me. God knows there's enough people out there already unhappy with me..I don't need to add to the list
Any rod epoxy works very well also, this is basically what Envirotex is. These finishes have a flexability to them so they work best on lures when your trying to work with water intrusion.
