Hello all! Just got myself an Xterra and was wondering what product I should use for handles and siding. Not too sure what the dealership was using, but it's been about a week and now it looks like white crust is forming??? Just looking for something that will make it shine and not cause any long term damage. I'm sure this seems like a pretty stupid question, but I've never owned a vehicle that I actually liked and wanted to take care of before. : )
