a guy on here (i think a younger guy) was building a ranger and had his bed off and took some chemical stuff and it ate the rust off then painted it outside. i thought it was a v8 build but i couldn't find it. i believe he custom painted his whole truck but it was a few months ago i saw it so i don't remember for sure. if anyone could link it to me i'd appriciate it or have any good ideas for how to get rid of rust on the frame without sandblasting.
