Not a problem. If you are just starting out I would recommend the following points to work on:Refresh on what Bullet said earlier about always finishing your model before playing around with textures, skipping out steps is the downfall of a lot of people. Research the various techniques for builing cars, my personal favorite is, mapping out Nurbs curves, lofting the panels then converting them to a low poly mesh. This way you have a quality edge flow but your panels are different pieces of geometry (as car panels are in reality). after you are happy with your model, prepare your UV's, extremely important if you intent on adding additional specific detail such as rust, stickers, and mud etc I may well start from scratch over the next week and put a tutorial together for a shader network dealing with car panel rust, its something I've not really looked into before. If you haven't solved your issue by then i'll post it here for you.
