I want to wax my Altima, but I'm unsure if I should do it or take it and have someone do it. Because when I had the SUV I let someone do it for me and it got on the trim and parts fo the bumper and stained. It did'nt look good so should I just take it somewhere and pay someone to do it?? Or I heard about getting car wash that already has wax in it. Has anybody used it and how is it?
