Ive got a 99 Basscat Sabre that Id like to upgrade to the newer dome-style Sabre decals. Ive tried pulling up, scraping with fingernails, and scrubbing with goo-be-gone and rubbing compound and have not had any luck getting the old decals off. The silver glitter underneath the decals has been the most challenging to remove. It seems like they are almost impossible to remove! Any ideas how to remove successfully without damaging the fiberglass? Or am I just out of luck and need to slap the new ones over the old ones??
