Hi david I fitted a glasfibre bonnet to my fulvia S2,
I bougt a spares car and the bonnet was fitted to it. I don't know who supplied it. I painted it black so you don't notice any ripples on it. A frirend of mine bought a Fulvia fitted with a glass fiber bonnet and the bonnet looks the same as mine , there is a small flat spot on the left hand side just at the bend line at the front of the bonnet. I over came this with a small rubber block in the channel under the flat spot. I then bought a glass fiber boot lid from Omicron and it is a great fit, I painted this white the same as the car but I can see ripples in the top of it. I still think it's worth while fitting them, No more rust or trying to make an alloy one fit.
