Black Ice™ is a special two part epoxy paint. It is applied in a spray and it adheres to the aluminum and will never flake or peel off. The semi-gloss finish gives any radiator the look of an original copper/brass unit. The total thickness of the dried product is only .005” thick and it will not affect cooling performance.

The superior quality of a DeWitts® radiator begins with a manufacturing process that is controlled 100% in house. Every core is assembled and brazed in Howell, MI to ensure excellence throughout the entire build. DeWitts® is the only USA aftermarket radiator company to own an aluminum Nocolok® brazing furnace which allows for production of a superior, epoxy free, aluminum core.
