Is there a spec sheet for the fiberglass kit you plan to use? That should give you the max temps for the material. Is the air filter gonna be a ram air type where it will stick out of the hood? That should be ok, with air flow to cool it. I've heard of older corvettes having holes burned right thru the hood (fiberglass body). You put on a chrome air filter on and open up the hood at a car show and the sun shines off the chrome and acts like a magnifying glass. Like burning ants with a magnifiying glass.
I figured I would share my findings with everyone. . .
They do make and sell hi-temp epoxies. They are expensive ($180~$300 per gallon) but have heat ranges from 300F - 1500F.
I did find one brand of resin that should work for this intended application. It's made by a company called Hexion and has a Heat Deflection Temperature of 130C (266F) which should be more than enough.
I want to contact their tech department first, but this is looking like the laminating resin I will go with when I do get around to it. Also, I did find a dealer on Ebay who sells the 1.3 gallon kit for under $80 which ain't half bad
never did find anything on that urethane stuff, though I didn't search THAT well. . .lol
