Funny Lesson Learned:
Upon an inspection between compounding panels, I noticed a big scratch that I had missed above where the two doors meet. I got my tape out, and spent about 15 minutes taping off everything meticulously. Then I changed pad sizes to a 4" pad on the PC, moved the extension cords to the other side of the garage to where the scratch was, aligned the light so I could see, and right before I began,
... it wiped right off.
LOL
very nice man
