Another vote for Turtle Wax Ice, although I haven't tried any of the others. I use it because i can use it on everything - metal, fenders, hardtop, handles, etc. It keeps things easy - which means I'm more likely to do it. 2+ years so far and everything still looks great.I have been using 303 on mine and turtle wax ice on my daughter's. Both potions work visibly equal. I tend to like the turtle wax ice more because I can use it on metal and plastic.
