zaugrishak5150 Posted April 5, 2010 Report Share Posted April 5, 2010 Hey guys. I recently bought a vibrating lure mold and made a bunch of 'em. I cleaned them with denatured alcohol and painted them with nylon paint, then sealed with UV Flash seal coat. After fishing them for awhile, the paint came off. Should I use sandpaper on the brass before painting?? Anyone else had this issue?? Quote Link to comment Share on other sites More sharing options...
BobP Posted April 5, 2010 Report Share Posted April 5, 2010 Unless your finish is sheeting off the lure leaving clean brass, it isn't a problem caused just by not sanding. There are various possibilities but most often, the problem is that your top coat is not durable and waterproof enough to withstand fishing abuse. I've never used nylon paint or Flash Seal so can't say judge compatibility or durability. I lightly sand brass spoons, shoot them with water based acrylic paints, then dip them in a solvent based moisture-cured polyurethane (in my case, Dick Nite, which is designed for spoons). The top coat soaks into and through the acrylic paint to bond with the brass, making a durable finish. Unfortunately, you just can't mix and match solvent based coatings. If their solvents are not compatible, or if the solvent in one layer is not completely evaporated before applying another coating, the paint will bubble and wrinkle, or fail to adhere. The solution is either to use coatings that have been tested by others and found to work (as above) or try coatings designed and sold as a compatible "family" by one manufacturer. If your nylon paint manufacturer also sells a compatible waterproof top coat, you might try it. Quote Link to comment Share on other sites More sharing options...
