Let harden then sand before second coat....?

Last time I looked- fiberglass doesn't burn.
Fiberglass has a softening point of 1555°F and a melting point of 2075° F.
And I very seriously doubt you'll get that out of a "torch" (with exceptions of course).

Cure, sand and recoat. Good luck because it will be very hard to sand with anything less than diamonds and then it will be difficult not to cut through the coating. You will not be able to sand it like normal house paint.

Don't know the melting or flash point fo the fiberglass. Don't know the temp at the head of a propane torch. Do know that plenty of contractor and DIY clients have used propane wands to successfully mitigate fiberglass before applying resin coatings.
Propane wands are used for a variety of reasons - deicing sidewalks, weed abatement, torch down roofing, cooking chickens on the run, dealing with fiberglass in concrete before coating with epoxy.
There are times when the fibers are almost impossible to see beforehand. What happens is that when coated they swell up and a seemingly non-issue becomes a big issue.
We had one client swear that our epoxy just formed these small spikes all by itself. Took some time to eventually convince him to get on his hands and knees to look at a spike with a magnifying lens - sure enough he could then see the tiny fiber in the middle of the spike.
If they're not too pronounced you could just coat over them. The next coat of epoxy will cover them to a degree, and depending on the density the flakes will also mask them. It's very much a case by case situation.
It may be easier to just buy more flakes and do a very heavy broadcast.

Really?
Then what's all that "hairy stuff" in this picture? What's actually burning is the gelcoat and resin.

Can you post a picture? Curious what this looks like.

In the past i have notice that higher mil thickness epoxy avoids much of the issue.

It tempers the glass, and if touched it falls apart. After you torch it, you need to broom it well.
