A Buck (old bonnet) is a shape you use to make the mold i think.
You use the mold to make your bonnet.
Chopped is what is used most often is cheap and easy to work.
Woven more expensive stronger harder to work.

But you have to buy it to look at it ?

I bought some a GRP kit from www.glasplies.co.uk and found them helpful. In my case I needed to extend my nose cone by 40mm. It was my first time with GRP and was easy to do but I was only adding a strip into the nose cone. I was supplied a thin, smooth, piece of glass mattting and some corse matting plus resin (+ catalyst) and filler. Plenty of it for £35.

I have to say that to make a buck is some going IMHO. Then there is the gel coat to add too (I assume). Personally I would go to a fabricator and ask them if they could make a bonnet in ali - it should be easy for them as they have the rollers, etc, to shape it. I did that for my first Rush when the one supplied was too short.
