As far as I can tell, during the proccess of bodywork and primer, I ran short on my black primer, so I used some gray(same brand and type just different color) on the roof and sailpanels. Where ever the Gray primer was used I had bubbles(tiny) rising under the paint in various places. I believe the Gray primer did not catalyze correctly allowing moisture underneath.
In the mean time I have stripped top 1/3 of car and going back with a two tone Black over Blue scheme.
