The Mastercoat® Difference. Mastercoat® Primer / Sealer / Surfacer Stops Rust Longer Than the Others.

Mastercoat® Permanent Rust Sealer/Surfacer/Primer is the industry standard for all types of projects dealing with rust–from bridges to antique cars to subway systems. Unlike epoxies, Mastercoat® Primer will run thousands of hours of salt spray resistance. Automotive epoxies will generally run 500-1000 hours. Many shops use our primer as a base to prevent comebacks. Buy Mastercoat® Primer here!

Rust Remover For Cars \
This 1938 Packard radiator shell was severely pitted under the hood ornament. Three coats of Mastercoat® Permanent Rust Sealer Silver followed by lacquer primer and paint, produced a flawless, show quality finish. Mastercoat® Silver is the ONLY type of moisture cured urethane that is air tight! Resin blocks the moisture, and aluminum pigment cuts off the oxygen. Unlike the others, Mastercoat® Silver is also UV STABLE, paintable, sandable.

What makes Mastercoat® different than the others? Click here to find out!

The MasterSeries Coating Line was founded in 1988 because we wanted the most powerful rust sealers and topcoats in the world. Our permanent rust sealer has demonstrated for the last 30 years that nothing outperforms it in salt spray tests. Our salt spray tests run from 8000 to 14,000 hours. Our AG111 anti-graffiti subway coating withstood constant washing with solvents and alkali cleaner, when used on NYCTA subway cars. At the end of 10 years, the subway cars still maintained a high gloss and color retention.  This is excellent for chassis and underbody protection on any vehicle.
