i'd use no thicker than 2mm plate and they need to go from point to point on the bonnet.

make a card template first then transfer them onto steel.

BUT there is more possibility of it cracking, as fibreglass expands and contracts during heating a cooling at a different rate to steel.

but 2 bits or metal side by side will not expand/contract at the same rate either

this guy is in his late 40s now and has been doing things like this for 30 odd years, started life building full size airplanes and has been doing VW campers and bugs etc on the side for years untill he set his own custom 'shop up

has a porche engines camper van and VW buggie with scissor doors and mental wheely bars etc that he made himself

I was just thinking that you could run into the same problems that you do when fitting fibreglass bonnet vents, thats all...

Do you need to shape the metal after its cut, like bend it in a slight curve like the bonnet does.
