Ok, I have lived with this long enough. The passenger door on my z32 is bubbling in the sunlight (ie. it lifts and you see bubbles). The rest of the car is fine, so I suspect they didn't use enough glue or the glue is decaying. How does one go about fixing it? Any ideas?

Best guess without removing the whole thing: as fine a hypodermic needle as you can get (if you can), put masking tape over spot, puncture and inject glue, press from needle out to spread glue, remove needle, clean any glue that seeps back out, press, clean additional glue outage, keep pressure on (with plastic backer) til it sets. Try to get a glue that can be removed with mineral spirits, not acetone, xylene, etc.
