Yesterday, washing the truck, I found 2 welding spots on the top, rear, right side of the roof where the "groove" for water to driff down. They were painted over(factory paint?). They were not on the left side of the roof where the "groove" for water to driff down. They look like rusts spots. Any of you see this on your truck. BTY, I also see black painted caulking on it too. My truck is black. The paint look like it's original paint from manufacture.
