This DP-60 Rust Proofer Spray 400ml is a high-performance anti-corrosion spray that provides exceptionally long-lasting protection to steel surfaces. DP-60 contains elastic polymers that create a tougher waxy coating that is more resistant to abrasion than normal wax coatings – this property enables this wax to protect vehicle undersides for prolonged periods. Unlike traditional bitumen underseals, DP-60 will not peel. Peeling underbody coatings trap water against the steel surface, accelerating corrosion. DP-60 forms a touch-dry, brown, wax-like film. DP-60 is able to arrest existing corrosion and to provide long-term protection to pre-corroded and corrosion-free surfaces. DP-60 substantially outperforms competitive material in salt-spray trials under conditions of spray. Performance should never be overlooked as vehicle undersides and cavities are always exposed to this attack from winter road salt. Similar to Waxoyl.
