Buy some candles, melt them down in a pot and drag the depower line thru it. Squeegie as you go. Let me know how you make out. Anything’s got to be better than surfboard wax.
BTW, I own a paper converting factory that makes waxed paper soo ... I know a bit about wax. Like any commodity there are diffferent grades , in this case, based on purity. The cheapie candles made in China are probably gonna smell like roses with a hint o’ refinery. So you might want to go all out and pick the heavily scented candles. Oh yeah, don’t over heat the wax or it will blow up in your face. The flash point is not that high. Seriously.
