Body-Tec? Amber Rustproofing matches OEM appearance while providing superior rust protection. Abrasion resistant coating will flow into hard to reach seams. Designed for replacement panels or new car rustproofing and restores the repair of existing corrosion protection to original specifications found on the interior of fender and panel replacements. Note: Amber Rustproofing is not recommended for use on exposed areas such as luggage compartments or engine bays, as the material remains tacky after application.
