Unwrap UV from Vehicle Model

[Simple0x47]

Hello people.

Today I've got a question because I couldn't find any answer to it for ZModeler so here I'm. The thing is that I want to make a vinyl system, for which thing I need a material which would cover all the vehicle parts except the wheels and the exhaust, the thing is if I make a material selecting those parts and assigning the material to them the vehicle becames transparent when the material has any transparency ( I know it's normal ) and the answer I'm looking for is the way which could give me the possibility of having that material covering all the vehicle without affecting it's 'solid status'.

Thanks.
