I wash my car a lot...I've noticed the dip gets dirty quick..which is a pain and I wash and wax more because of tires kicking up salt and crap. I need mudflaps..I have stuff to make my own but I absolutely cannot figure how to mark out holes. I used a crayon and paper to shade over inner fendwheel well and tried that way..but it just does not work..anyone know of any samples or diagrams that can be cut to size for mudflaps?
