what r c4d's and how do u smudge and stuff. and say it so i can understand lol :/
a C4D is an effect.

like that. if its an effects one, like those, then you can put it on the top or under the render using linear dodge as the blending mode (drop down box above layers)
smudge, well you download some smudge brushes, mess about with the settings a little if you want, make duplicates of your renders with CTRL+J, and smudge them, to blend.
if you want ill get you some tuts to do that are about your level, although they wont be on cars, but REALLY good for what you need them for.
