If I were to use dustless blasting on the cx; Will it leave a conversion coating so to speak because of the said rust inhibitor in the water? I was planning on using dustless blasting since the last guy to paint my hatch kinda did **** basswords on the roof panel.

He reseated the windshield and while it was out he was supposed to paint the roof but after I hear the windshield was in I stopped by and he was doing the bodywork to the hatchback spoiler jamb area. I cant believe it I caught him I was told he isnt a hack. So its blistering there and the spoiler is rotting again, I can see the masking marks now. I have this old man who paints telling me I gotta blast it, this is thin metal and Im scared of abrasive blasting the roof.
