Hadley Posted January 18, 2016 Report Share Posted January 18, 2016 Can KBS MAXX Clear be applied directly to clean, sandblasted metal? I am looking for a clear sealer to apply to an old steel boiler that has been sand blasted. I do not want to change or add any color but want to protect it from rust. (the steel is inside) Quote Link to comment Share on other sites More sharing options...
