Wire wheeling, scraping has been my business lately.
Got the frame mostly clean going over it with one of those paint stripper wheels and sanding to get clean metal. Doing it a section at a time so i can prime it before it has time to rust. Having it sandblasted would have been smarter. lol
Also patched a piece of the frame where to p.o. done something torched it beat it something where the auto trans cross member bolts up. I also cut out the left over manual trans cross member ends they didn't remove.
