Ask painter if the waves can be sanded down and re cleared....I painted my fender 3 times before I got it right....I know you paid big bucks for this and you expected it to be right...
The nicks are probably from the shipping company...they care nothing about fragile or other such words...my point is even if they sent you another one...it could get here in worse shape...been there and done that...
Orange peel can be removed by wet sanding....
