I went to a public auction with a lot size of a house of apple computer things and received an Apple powerbook 5300c. The top of it is really messed up, like a glue residue left on it by trying to clean it with an incorrect product to use an left this whit stuff all over with it looks like somebody took their fingernails and tried to scratch of the white stuff. How do I remove this white stuff, or can I repaint over it and paint it black with a plastic paint? Or can I do that without messing the top up even more. How do I repaint the top or get rid of the white stuff? Also, where can I get software for it and games, etc. Thanks.
