And, if you don't happen to have any Bug and Tar Remover, a good ol' cleaner wax will do the trick. You just have to use a little more elbow grease than the bug and tar remover, but you will get equal results. Just make sure to wash and dry the Pathy first. I use my reliable Zymol cleaner wax, or Meguiars cleaner wax. Both waxes do the job equally well.
