I’m curious to know how you blend the clear coat into the existing poly without witness lines. I’ve never managed it without having to clear coat an entire section. Masking at the neck joint would work well for this repair.

Robbie O’Brien demoed a spot repair of a waterborne finish he uses, and after polishing he had witness lines and essentially said “you can’t make this repair invisible so I’d just overspray the whole surface.”

I wonder how autobody shops do it?
