Amber Rustproofing No. 4424

Designed for use on replacement panels or new car rustproofing, the Transtar Amber Rustproofing, No. 4424, provides superior rust protection. Its abrasion-resistant coating flows into hard-to-reach seams, and restores the repair of existing corrosion protection to original specifications. Remains tacky and flexible once applied, the kit comes with an undercoat gun and rustproofing wand.
