I have two spots on my 2011 Yukon XL that the paint is bubbling or blistering.
Now here's the bad part, I've sanded it down and its all SURFACE rust not coming through on the back side. The metal under the paint/primer thin rust layer is CLEAN and solid.
So I sanded, cleaned with goo gone and isopropyl, reprimed and repainted...and low and behold over the winter blisters and bubbles in the same DAMN spot.
Anyone have any idea why?
