I figured out how to make a half decent fibreglass/CF bonnet:
- Using the existing bonnet, cover in foil and glass over the top (same goes for the bottom if you want the re-inforcement structure which is a definate)
- I reckon 3 layers of glass either side should be strong enough, not too sure how i'd go about sticking the 2 sections together so they'd be the same height/profile etc as the original metal bonnet.
- Sand, sand, sand and more sanding. Layer of bodyfiller, more sanding for a PERFECT surface finish on top.
- Send to mr. CF guy and have him do the rest (sticking it in an autoclave for any decent strength and light weight).
