I am working on cleaning up and prepping my hood for a repaint. Had paint over surface rust. I have stripped the paint with chemicals. Most of the surface rust came off with some sanding. Now I have small pockets/divots of rust and a little paint, subsurface, on the hood that I need to clean up. OTHER than media blasting, what is the best way to get these pockets cleaned out? Someone had told me about using a "reducer" to "lift" the rust out. Any truth? Help please...my 1st attempt at this type of detail. Thanks!
I use phosphoric acid and a used wire brush. I will take the pits out and leave clean metal. A used brush pictured below counterclockwise by hand or in a low speed drill will work well. Be sure to keep the metal wet with the acid. When the acid is brown wipe and use new. It usually takes a few hours but you will be left with shiney metal. Rinse with water when done to neutralize the acid. Ray
