March 15, 201610 yr comment_3600 I ordered some products to paint my motorcycle frame. The frame is in good shape overall with only a few very small rust spots. I am concerned about adhesion on such a clean surface.I know the RustBlast etches the metal but I confused whether the etching properties only work on rusted metal and not clean metal. So far, I have striped the factory paint and sanded with 150 grit. Should I go ahead with the KBS system from here OR could I sand up to 220/320 grit?

March 15, 201610 yr comment_3601 RustBlast etches rusted metal and clean metal surfaces extremely well. The smoother the surface, the more etching the surface needs. And while the surface does not need the 320 grit scuff, giving the surface a 320 grit scuff would not hurt anything and could only help adhesion. Please review the complete RustSeal Directions and let us know if you have any additional questions.
