I just paid my truck off (YAY me) so I decided to do some major detail, I've always used Meguires after washing but this time noticed it needed a little more in a few spots so I bought some colored wax and WOW took those swirly spots right out (one of them pretty bad where I accidently hit it with chrome polish oops) Anyway, now that the truck is 4 I plan to wax twice a year, meguires other times
