      Larry: After you read my thoughts go to a website of bodymen from around the country I highly recommend to you. Autobodystore.com and go to the discussion page and do the same thing there that you did here. First possibility is solvent pops or lifting due to a chemical stripper. Also the fiberglass looks like the glass strands, look like what is called dead glass. This is what happens when it is heat damaged. The resin is damaged and all that is left are the strands. autobodystore.com to the discussion page now. Good Luck!

        If the problems are limited to the deck lid and quarter panel (and the soon-to-be-junked trunk), they won't be too terribly difficult to repair. I'd probably try to leave it out in the sun for another couple of weeks if feasible to be sure whatever was under the paint is gone and that no more ugly spota appear. I would feather back an area at least 3-4" from the damaged area before reglassing, and then let the repair sit in the sun for a few days for good measure.

          Larry,

          What I see here is resin starved dry fiberglass. This panel did not have adequate resin when it was made. I've seen this condition hundreds of times on composite bond form tools at the aircraft plant where I work.

          I wouldn't expect this on an OEM panel, but would say it could be a very common occurance on reproduction panels.

          If I were you, I would take the suggestion already given an just grind out the blisters and handlay some new fiberglass matting and soak it up good with polyester resin. Let this cure in the sun a few days, sand smooth and then finish with bondo and more slick sand to match the adjacent surfaces.

          good luck,
          tc

            I have my fingers crossed that I will not get any more blisters
