October 7, 201213 yr comment_2181 I note most of the rust that is being removed in videos is basic surface red iron oxide. I have an area around the windshield opening of my 51 Chevy truck with serious black rust and holes. I plan of repairing the holes with epoxy putty. My question is what to do about the black oxide in the bottom of the deep pits. I have used an HD twisted wire wheel and die grinder to remove most of the rust and rot. I have even hit the area with a media blaster using ground glass but there is still a lot of black oxide spots as you can see in the picture. Will Rust Blast take care of these black rust spots? Should I use the epoxy putty directly on the dry and treated metal or should I paint with Rust seal then apply the putty?

February 28, 201313 yr comment_2648 If you soak those spots with RustBlast long enough, the RustBlast should take care of those spots for you. Â The RustBlast will leave a prepped surface ideal for RustSeal. Please let us know if that helps and if you have any additional questions.
