Ok, so my 12 year old son is starting his little league season this year in about 2 weeks. They are allowing the use of wood bats this year and he found a game used bat on e-bay of one of his fave players. (frank Thomas) so I bought it for him rather cheaply and surprised him with it yesterday. He was so excited when I told him he could use it in his games this year. He swings it quite well, however at practice today the coach told me he wouldn't be able to use it with the pine tar still on it. I have tried everything to get it off but am having absolutely no luck. What is the best way to remove the tar without ruining the black finish on the bat? It's a pretty thick coat. Any ideas would be helpful......
