I don't like to rinse with the hose or spray bottle because there is usually a lot of other bare metal that I don't want to get wet.
I am thinking about taking the surface to bare metal with the DA, maybe a little wire wheel in the pits, then treating the area with pits with POR15 or Zero Rust. When fully cured, DA again, which would leave the POR15 or ZR just in the pits. This car is getting a vinyl roof so I wouldn't even worry about filler. I would just epoxy over the whole roof and call it good. Has anyone tried this?
