For extreme conditions, our silicone-modified polyester (SMP) formula means stronger protection, more durability, and better metal paint endurance.

Bigger, bolder silicone modified polyester (SMP) coatings are cutting-edge formulations each feature a two-coat finish recognized for its durability, offering even stronger protection and endurance during extreme conditions than its predecessor.

Created to withstand most anything that comes it's way, our specially formulated WeatherXL silicone-modified polyester coating is designed to go where it will be abused - maintaining extreme resistance to abrasion, chipping, and marring with tremendous color and gloss retention.
