I could use a little guidance from all you fiberglass wizards...

Having applied (with care) my heat gun to several areas of the lower cowl, bubbles started to form in the gel coat...
Sanding away the gel reveals air pockets trapped between the gel and glass beneath so obviously, if these cowl pieces were manufactured using the vacuum bagging process (which I doubt), Lancair was pretty light in the vacuum department! I suspect they were wet layups to begin with.

So the question is this. In normal use and with hot engine compartment temps together with baking in the sun, do bubbles eventually start to form and become visible in the paint, especially on the upper cowl??? Should I remove the gel and fill all voids.

Best wishes to all for a MERRY CHRISTMAS!
