^I still have that IIci! Still works great after I replaced the missing parts. Never did have time to get all of the paint off though.

Don't have any clues about the Lisa, but a good way to get off the paint is using Dot 3 (ONLY) brake fluid. It won't harm the plastic at all, and it works very well. Rubbing alcohol works too, but it can eat the plastic's texture.

EDIT: LOL; this was my 1337th post!
