Tom, are the bubbles near the fenders where the side pipes exit ? IF SO , your pipes are too hot from either your distrbutor timing being retarded too much or your combustion mixture is too lean. check it out, and once corrected the bubbles most likely will recede. continue driving if you are too retarded (car ,not you personally) or too lean and the bubbles will worsen. spf paint is outstanding, so if your problem is not near where the pipes exit thru the fenders, then you have a rare example . you most likely got your car at Dynamic ( if bought new) and if you are not too far from them go back and have them check it out. bill.
