I have several, they have been put away for several years... The "wax" can get expensive, depending on what you are looking for...

I started using colored hot glue gun sticks, plus they won't crack or flake off... I heated it with a torch lighter, it's faster to melt and easier to dab rather than drip on the surface. The come in a large range of colors, maroon, silver, gold... You name it it's there.

This is very old school and a great idea...
