Hoffman_I have always just used skate wax and there's a lot of good recipes and tutorials of how to make it online. I normally make it by melting some tea-light candles, a little bit of some sort of oil and crayons for color in a can in a pot of water (don't melt it in a pot, because it'll stick to the pot, and that's a just mess). Then I pour it into a tin foil mold. You might have to play around with amounts to find the right mixture but as long as it's solid in the end it will work. Also DON'T POUR IT DOWN THE DRAIN it'll solidify in the pipes and fuck your plumbing up.
ParryWithAnAI have a few left I will update the stock now.
