Exterior Shine

[igotjam]

Years ago whenever you bought a new car they tried to sell you some type of coating to protect the finish and reduce waxing. The type I remember was MING PLATING but it went by various names. My father had it done on a couple of new cars and as I recall it actually seemed to work. Over the years I have heard less and less about this. Perhaps with new automotive finishes it is not reguired?
Anyway, I just ordered a new fifth wheel and they offered a coating called DIAMOND KOTE which sounds like the same thing. The dealer states it will prevent fading of my painted graphics on the Gel Coat, guaranteed etc etc.
What do you tHink? I sure would like to reduce waxing and it will be parked outside always.
