I just got my 2009 Sierra back from the body shop, I had the inside of the rear wheel wells painted and a fair size rust spot behind the drivers side rear wheel repaired then tonight as I was admiring the nice job I noticed a brown patch on the bottom of the passenger door, it is about 6 inches long and about 1 1/2 inches high at the bottom edge of the door, the paint just fell off of it, I looked the truck over when I picked it up and did not see this so the paint was just hanging over it, I have had GM vehicles all my life but I never thought I would see a 6 year old vehicle rust like this, it only has 130K on it, GM I am very, very disappointed in you and I just bought another Buick. anyone else having paint problems
