I'm trying to save my mower deck, it had a poor powder coating I didn't realize, has been aggressively rusting. I needle gunned, wire-wheeled, and applied ospho, let it set overnight and now I have crusty bubbly black patches everywhere. I don't want to paint over that. I tried blasting it off with my pressure washer, partially effective, but not really. Is there some other face & respiratory melting hazmat I can apply to dissolve the black crust? Will applying more ospho do it?
