This seems like a stupid question but I have to ask because I'm confused, and the answer is probably really simple. How am I to smear the bar of compound from stewmac on the guitar when it's as hard as a brick? I know the obvious answer is to get it wet but water just beads right off the bar, as does any kind of paint thinner. So I just don't know how to get it to spread. I have never used a hard bar of polishing compound. In my experience they have always been clay like.
Thanks for the help,
Dustin
