Mike Posted June 16, 2019 Report Share Posted June 16, 2019 I previously coated parts of my frame with rust seal about two years ago. I am now finishing the rest. Will rust blast applied over existing rust seal etch it and make it permanently chalky/white or will it wash right off during the rust blast step?

KBS Coatings Posted July 10, 2019 Report Share Posted July 10, 2019 RustBlast sprayed onto fully cured RustSeal will not harm the RustSeal and any residue will wash off with plain water. 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...
