I looked at PepBoys for a wax that will last as long as possible through touchless car washes and I'm confused. Who makes the longest lasting car wax, Nu-Finish, Mothers, Turtle wax 2002, Kit Carnauba, Prestone, Zaino, Meguiars, Zymol, etc? Does anybody have information or an opinion on a good wax? Thanks, Dave M.
