that's all that I use as far as stripping and buffing. The black one, harder, to remove hard rocks, the other one more softer to buff out. After I'm done I just use turtle plastic restorer and wipe. Just remember if you do decide to do what I did, make sure you are not stripping or buffing in one spot for too long and move around.

Just wrapped up with the last one

3 rusty bolts that about to be cut off today. Lots of rust under the plastic.

 

Lookin' DAMN good! Thank you for the clarification!
