stripping a patina Duster hood

mad dog said

i was just reading a forum based on this and ospho users said the same thing, they said to NOT let it dry and if it does dry to reapply ospho and wipe it clean and use plenty of water... i was thinking that the ospho needed 24 hrs to do the rust conversion, 10 minutes doesnt seem long enough, maybe it is....

How bad is the rust?? You said it was DA'd and blasted? There shouldn't be much left after that. I think you'll be surprised how quickly that **** works. For large sections of sheet metal, I get what I can with a scotchbrite roloc and hit what's left with a spray of acid, let it sit for a few mins and clean it off. That's the process I used for the roof panel in post #12. Only a few small spots needed more than one application.
