One very loong pass, yes. Actually, I did do a second pass over most of the truck, so lets say 2 long passes. Took me a total of 4 solid polishing hours to do the truck... But since I'm not confident with rotary on black, I had to be patient with the 4" PC pads.
I wasn't polishing in the sun, so I had to wait for the sun to hide behind the mountain before I could polish that side of the truck... I will try to get some full-sun shots soon.
Up close the before is a hazy grey of scratches, and the after was dripping wet black except for the few random scratches..
PO85RD even got out most of that one big scratch with enough working!
EDIT
The first picture, the rear fender is done (Polished that with Optimum Compound in the sun, but wasn't quite as satisfied with the removal ability)
Whoops! It is NOT PO85RD! It's
PO85U, much more cut.
