Great stuff. I have the pressure washer. It's in pretty good shape. It's mostly just the typical surface rust. The wire wheel will get the bulk of it. I just want the ospho to get the rust in the nooks, cracks, and crannies. Sounds like the scotch brute behind the washer is a good tip too. Thanks. It's my frame so no buffing on it. But I still want everything to last on it. Thanks!
