Hi Will, Depending on the result you want to obtain, you have several choices concerning the finishing of your model. For sure Steve will give you a complete answer as he is an expert in clay modelling. I can only talk about what I've tried. First of, using steels you can get your final surface very good, it means very soft, slick without waves or bumps etc... I think it should be your main goal because all the other finishing techniques will require your surface to be as good as possible anyway. You can also paint the model, ( using special paint because there is oil in your clay ), until you get a top automotive finish. For this you will need some spray-painting skills and access to a spray booth for your security and a dust free result. Another possibility is to make a mold from your model. The mold can be made of a hard material ( plaster or composite material for example ) or flexible material ( silicone etc... ). The silicone molds work great , you just have to have a basic knowledge about mold making and to spray a coat of strippable vinyl or paint on the model ( before the molding process), because otherwise if your clay contains sulphur the silicone will never cure ( or/and other problems will occur). Once you have your mold, you have a large choice of casting materials , from polyurethane resins to carbon fiber, plaster etc... As you can see there are lots of solution and that's the beauty of it. As Steve previously said, you should test some of them before trying on your model. Can save you a lot of troubles ! See you Seb

Hi Will, Seb has just about summed up the answer to your question. Ensure that you steel the surface of your clay to remove as many of the ripples as you can. If you are going to paint the clay, seal with an appropriate medium such as shellac or latex paint. This will help the primer in sticking to the model without it wanting to peel away. Surface the primer and apply a finish coat. Alternative is to take off a mold and produce a hard model from the mold. There are plenty off options here, it's a case of which one you prefer. Good luck, post us some images of your results. Steve A
