Hi Woodsy, I have recently restored a Century 21 Sam Loover's Car and thought it might be of interest for blogging. When I got hold of it it had no bonnet or rear wing and there were a few melt marks in the bodywork.
I scratch built an opening hinged bonnet and a new pivoting wing. The melt marks were sanded and polished out. The bonnet and wing were made from scrap plastic and sprayed up to match the body colour. Mixing the paint to the right colour was the biggest challenge!
