Will fiberglass ever stop "wiggling"?

I would be curious to hear what it is also. It's been a regular practice for decades to spray gelcoat early Corvettes stripped to bare fiberglass (they received no gelcoat by GM) during re-paints. I sprayed my own and it's some tough stuff and a mess to work with - but as long as put on to a specified thickness, it will seal down fiberglass and repairs like almost nothing else. Some painters have converted to epoxy primer on bare fiberglass but on a rough body I think many of the pros still like glecoat. I haven't read about anything like a carbor fiber based primer over on the Corvette Forum yet.
