No big deal FH. I was a fleet re-finisher and bodyman for a large transportation fleet for number of years early in my career. I won't go into too many details but sandblasting was a method we used, I was never thrilled with it for fiberglass as it left too rough a finish and required alot of powersanding afterwards. Guess we were doing it all wrong. We used chemical strippers for certain jobs mostly on fiberglass that had too much paint buildup over the years. I've used the aircraft strippers on boats and vettes too and never had any issues, it does require a thorough cleanup (and it will soften bondo). I've recommended it on here before and never heard any negative feedback so other folks must be using it right.
Well, enough rambling on the subject, have a great afternoon.
