To make your own waterproof matches with quick-dry nail polish, paint one side of the head and a half-inch of the stick. Blow on the fresh paint to dry it. Then paint a neighboring stripe and blow to dry. Repeat this until the entire match head is encased in quick-dry nail polish. If you don't blow-dry the polish, it will soak into the match head and ruin it. To use a polish-coated match, use your knife or something rough to scratch off some of the polish on the side that you will be striking.
