How to? Fix a sagging fiberglass hood... Heat Resistant Foam?

Thx FB,
Some good idea's there that will definitely provide a more effective long term solution,I did have foam on the pins (already compressed) and why i hadn't thought of something as simple as hose.....wellllll!

Having never worked with glass before I guess I better find a good UTube vid and figure a way to get the contour i'm wanting to replicate while the hoods upside down being glassed and curing..would shaped wood clamped to the curing hood be what i'm looking for?

??? Unless its really flimsy , it might stay the right shape with simple blocking and spaceing , upside down on a couple of sawhorses .??
