Depends on color and what you're after as an end result. A Barrett Jackson finish is worth it, a local driver show n shine definitely not.
Hoods and fender tops are looked at the most so maybe a "topside" cut is worth it? I have a Harley and it's cut polished on tank and top or fenders only... just a thought.
It's real easy to spend someone else's money but I'm not like that.
