Diamond black metallic, 17 month old and apart from a very light scratch caused by a shopping trolley on the passenger side rear wheel arch it is still perfect.
Use washing Mitt and AG body Shampoo, then AG Aquawax.
Wax the car with AG High Def Wax last September, have just rewaxed the car last weekend and it is perfect from a very hard winter no swirls!
IMO High Ded Wax is much better than Aquawax and should last the life of the car not bad for 36quid. Use Aquawax to finish the car off after a regular wash, always using Micro Fibre clothes.
