C2V3 is the bomb. I probably use about 5 gallons a year. ChemicalGuyS V7 is another excellent product.
Just use them as you would any quick detailer to finish the wash stage and for a final buff including wheels and glass.
hammer and chisel no that was Crystal Serum, C1 can be removed with aggressive pads if needed - but its easy to apply as long as you make sure the surface its spotless and oil free, spread it across small sections of a panel and remove any excess with clean good grade MF. keep the car dry for 24hrs
