We had this Audi RS7 in for a Gtechniq New Car Protection, the paint was in perfect condition so we had no machine work to carry out and went straight for adding the Gtechniq protection. Bilt Hamber Korossol was used to decontaminate the wheels and paint - lots of reaction on the wheels not much on the paint, these cars are transported fully covered. After letting Korossol dwell, we hot washed the car with a TFR foam, followed by a 60 degrees rinse.
The front and rear of the wheels were protected with C5 Wheel Armour and the tyres dressed with T1. With the glass treated with G1 and a full interior valet, the car was ready to go home with its new owner.
