I have been to every car show over the last 30 years of my life and I have never seen a paint job that didnt have flaws or develop flaws, regardless of how much money was spent by the owner.
Even if it looked good on the outside, just look in the door jambs, around deck lid or hood and you will find some bad looking stuff.
I cant make myself spent 15 grand for paint job and have that to look at. What happens to these cars? Just curious..
