Mastercoat® EXTREME Permanent Rust Sealer For Deep Pits

Condition New

WE'RE SORRY, THIS PRODUCT HAS BEEN DISCONTINUED. YOU CAN ACHIEVE THE SAME RESULTS WITH OUR ORIGINAL FORMULA PERMANENT RUST SEALER: SCOOP OUT THE SOLID CONTENT FROM THE BOTTOM OF THE CAN AND USE AS A FILLER. Do you find using metal body fillers time consuming and tedious? Mastercoat® EXTREME Permanent Rust Sealer® has you covered. Mastercoat® EXTREME from The Master Series Coating Line is the much thicker, higher build version of Mastercoat® Permanent Rust Sealer. Its duty is to fill in the deepest pits, with less work. It’s also toothier for topcoat adhesion and has a thick paste-like consistency for the deepest pitting. Like our original formula Mastercoat Permanent Rust Sealer, it will also stop rust and keep it from coming back. It's also sandable, UV stable, and toothy for good adhesion for one of our topcoats or any topcoat of your choice. It’s as easy as reducing and shooting through your gun to fill in those pits, even in contours. Ideal for vehicles, tractors, trailers, boats, outdoor fixtures, or anywhere rust occurs. Color: silver. One quart covers 100 square feet. Coverage is approximate.Use within one year of purchase.

Note: EXTREME is more of a solid than a liquid. Can be thinned with MCT101 thinner or urethane reducer for easier application. Do not use when the relative humidity is very high and apply thin coats for the best results.

SHIPPING: Ships FedEx Ground only. Ships to the U.S. (lower 48 states). We're sorry, we're no longer shipping to Canada at this time.
