    No more rust.™

    Time after time and test after test, Mastercoat always outperforms the competition. We adhere strictly to coatings industry standards for rust encapsulation. We do not sell black moisture cured as a permanent rust sealer like the competition.The Mastercoat system is the ultimate way to combat rust. It does 14,000 hours of salt spray, is UV stable, will not rust beyond a scratch, and will improve your body work dramatically. Compare that to POR 15, KBS, and the others.

  • Use anywhere rust occurs.

    Use anywhere rust occurs.

    Automotive, marine, industrial, around the farm & home--it has as many uses as you have imagination. Mastercoat is the answer.
