Fiberglassing Plastic Vent To Metal Bonnet

[Hungryhippo]

I want to cut a hole in my standard bonnet and place this scoop in backwards, flush with the bonnet so it acts as a vent. would it be possible to fibreglass the vent in place from underneath? Is there an easier way to do it?

cheers

If your trying to blend it into the bonnet, dont wast your time, it will crack, better off having a join and filling it with drip check, then painting it.
