Hello experts, Quick question here. I am spraying LPB on a strat and have some spots from the spray can spitting a bit. I warmed up the can in water, but alas. My question is what to do about the spots. Keep adding coats on top? Sand them out? If so, what grit? I know this topic has been covered but thought I would post it fresh because I am using a metallic LPB finish and not sure if that would change the answer. Thanks in advance!!
