Some vehicles, after a long period of time, tend to fade slightly in colour.
Red and Navy coloured cars are known to fade a lot quicker than others through sunlight exposure and strong car wash detergents. Although this type of problem cannot be rectified long-term (accept for a re-spray), it can however be rectified temporarily. By compounding the panels of the vehicle using a speed-polishing machine, followed up by a glaze and a wax, the vehicle colour will be restored and can continue to look fresh providing a regular coat of wax is applied.
Please ask a member of staff for more information on this.
