Thanks for the replys guys...
The major problem is, I live in Europe, and most of the materials used in the US are not available here, or have a different name, or different characteristics. I-ve never heard of these materials: acetate, clear plastic sheets from evergreen and vacu-forming. Maybe acetate can be found here, but it would be hard to find. The second problem is, there are no model-shops in the area. not eaven in a range of 200 miles. In fact there are a few shops, but they sell only models. I will search for the materials mentioned above.
As for the tyres... I don't want to use RC car tyres (eaven if they would be available), because I want to make it as accurate as possible. They mst be a the right size and need to have the original Pirelli profile.
What is the rubber-like resin? Is it a material similar to epoxy/polyesther resin (2 composites, no special technique required)? Just how hard is it? Is it only an alternative for not using hard plastics, or is it smooth like a real tyre? Which stores should have this resin?
The taillights are simple to make as far as I find the perfect material for the windhield. I plan to make it 100% transparent and use some semi-transparent red-yellow films/vinyls/whatever. The only hard part is the bottom of the tail-lights, because they are bent at a sharp angle.
Thanks again, I already found some great help here. I will update my site as I go further with my project.
