317Indy- Thanks for the trip down memory lane, I worked in new car prep when those were new

Heh heh, even in GA, I'm a little surprised it doesn't have any rust, given the build quality. He must've got an especially good one.
Yep, even with (mildly) abrasive polishes, you'll be OK. You sure don't want to remove more than you need to, but the pads are gonna scare you no matter how little you take off.
The SS paint they put on in those days is (or at least was when it was new) a *lot* thicker than the b/c *or* the SS used today. Today's SS is sometimes even *thinner* than the usual b/c. If the car has any stonechips, check out how thick that paint is.
The Meg's 3-step should work pretty well on that one, it's not all that different from the stuff Meg's makes specifically for SS paint. The step 2 product really will *feed the paint*, in this case the concept isn't BS.
Have fun and take pics if you can!
