KBS Coatings Posted May 26, 2016 Report Share Posted May 26, 2016 RustSeal is rated at a 7H on the standard pencil hardness test meaning RustSeal is extremely durable and able to flex with substrates that bend and flex. Please let us know if that helps and if you have any additional questions. Quote Link to comment Share on other sites More sharing options...
