Well there hasn't been much visual progress. All that is different is a little less rust, a lot less grease, and the cab fan smashed up on the ground. (figured that since the fan was rusted solid and missing parts it could go) as for the rapid strip discs, the knockoff of the Norton I got (think it was called Avanti pro or something like that) is only good at removing paint, not so much at rust, also it lasts for about 5 minutes, and costs like 2x what a wire wheel does. After I half wore it out on one small panel, I tossed it in the back of the barn, and grabbed a wire wheel.
