Ok paint gurus... I have a paint delamination issue. On the rear quarter, the factory paint (2007) started to delaminate in a small (quarter sized) patch. I put some touchup paint on the spot 9 months ago before my daughter took the car to SD to school. When she got home for the summer the spot was about 1" irregularly shaped, where the touchup paint was brushed on it stayed well attached. So I figured I could sand the delaminating area to well attached paint, prime and paint and clear to make it look a bit better and stop the delamination from spreading. I finally got to what I thought was good paint/primer and bare metal. I applied several coats of primer to the effected area, then 4 days later, wetsanded the area to smooth off any high spots. Al was looking good. I applied the touchup spray paint to the area and everywhere there was a interface between "good" paint and the primer the paint sort of wrinkled up. I got frustrated and said what do I have to loose, so I took it back down to bare metal and a "good" paint interface and just painted with top coat (no primer) same thing. I am NO paint and body guy, but I was able to do a rust repair on my daughter's Jeep Grand Cherokee that came out so good I amazed myself. WHAT AM I DOING WRONG??????
