if the paint is the same as the ibooks, try using 99% isopropyl, which is extra strength alcohol. I have heard of people using paint remover, or just regular alcohol. I have used the 99% isopropyl though and it works like a charm, on the ibooks. You might have a little trouble finding it though. I had to go to a hospital supply store, as 99% is harder to find than 70%.
