Well... My 7th grade science project or CONTRAPTION as you call it has saved me many many hours of scraping, wire brushing, and or chemical paint removers that destroy the environment. You have read several others on here have used or experimented with the process and concur with me that it really works. In fact Saturday evening I tossed my fuel tank hanger straps in, flipped them over yesterday morning because they were too tall to submerge all at once, pulled them out about noon and ran the Scotch Brite over them in the sink, rinsed them off, inspected them and trust me they looked like fresh factory stampings, squirted paint on them and an hour later hung the fuel tank in my frame. So I am now that much closer to having a RUST FREE 1994 B4000. But to each his own I guess. Don't like the idea.... Don't use it.
I forgot to mention... I took a look at the pic of your ride. It looks like it could benefit substantially from some tank time.
