But if you want to try acetone to clean off tape residue from your glider, please go ahead. Works great on plexiglass canopies as well! :P

Note that the statement about using acetone on plexiglass was meant to be sarcastic. NEVER use a solvent on plexiglass! It removes residue, all right, but then the plastic will craze, get brittle and crack, thus relieving you of all the extra cash cluttering up your bank account.
