I scored an old, neglected Peavey Fury bass with a broken pickguard. Peavey Parts is fantastic and had a replacement in stock, and only $20!! Just arrived today, so I have been refurbishing the bass. Almost done - time to peel off the plastic film - and - it is so old that the film will not peel off. the plastic is brittle and the adhesive is hard. I have to scrape it bit by tiny bit with my fingernail - it took 30 mins to do about 3 sq. inches. Heat made it worse. GooGone dissolved the adhesive remnant, but won't loosen the plastic. Any ideas other than ordering a brand new one for 3x the price?
