68 barracuda 383s "Driver Paint Resto"

yep we can never have too many tools in the toolbox when it comes to fighting rust in 40-50 yr old cars. I have to wonder how well those scuffing wheels mentioned by davescda holds up, I spend quite a few $ taking a complete car down to bare metal no matter what I use!
I like the Ospho where you have PITS in the metal, hard to get all the rust out with DA or any type abrasive, even a big wire cup!
