Instead of dipping each match in wax, drill several holes in a piece of wood so the matches stand up, spray them with polyurethane. After the polyurethane is dry, you have waterproof matches that take up much less space then ones coated with wax. And they are much less messy on a hot summer day sitting in a car trunk then wax coated matches that melt all over. Also they don’t seem to degrade as much.
