I use LiquidGlass Wax, on any freshly painted new car, or restoration; usually takes 2 applications to seal the surface, road dirt, rubber from burnouts, road bugs etc, just wash off with a general car washing, no cleaners/ compounds needed just gentle car wash liquid soap, the only thing is, if you start using LiquidGlass, you must continue with it because other waxes haze the surface, but it dose leave the surface with a wet look, and very slick!

I've tried all the others from Mothers, Mequires, Rodshop, etc, the LiquidGlass was by far the best IMHO on new paint that hasn't been "waxed"
