Looking for advice on prep and resealing of aluminum roof on 84 Toyota Dolphin. Roof is covered with old sealant that has degraded. Peeling in many spots, but impossible to remove in most places. I have tried scraping with a plastic putty knife (advised that metal can damage the aluminum), using a heat gun and carefully scraping with metal scraper, and Acetone. Nothing helps that much. Heat gun softens the coating some, but also melts a plastic putty knife (heat from roof and coating, not the gun). Wire brush on a drill has been suggested, but will that also damage the aluminum? Need suggestions for removal, prep (sanding, priming, recoating areas where coating is firmly attached), order of reapplying (removing vents, applying seam tape, products, replacing and sealing vents and trim, applying new sealant). Can Dicor Elastomeric Coating adhere to old covering once it's scraped and cleaned?
