Don't ya hate it when. Your finishing up something up. Final polish slidin all over with buffer. Like what your seein on panels. Then flip your buffer over to clean out pad. Then you see it. Base color in buffing pad.
Grandson thought Pa had lost it. LoL Turned out to only be on one of the fender flares. But still gotta fix it. Don't even remember last time I cut thru something. Even knowing what your doin. There's moments of uh oh's.
Wish it was the old lacquer days. When I could patch it up in a few hours. LoL

Happens to us all.

Fortunately not that often these days and makes it easier when we know how to fix it.
