Keeping the XJS clean

After a few successful years in the concourse scene a few years ago I had many different products and techniques for keeping the XJS as clean and shiny as possible.

I was reading the other day that one company now offer a valuating service which costs a lot and takes two weeks to clean your car using de-ionized water, cloths made only from the wool of little lambs and wax.

I know there is a lot of premium products out there now which calm every increasing levels of Carnauba wax. Having had a jar of 100% carnauba wax I can certainly tell you its rock hard and didn't even try using it on the car. The car valeter who gave me the jar used it in small quantities and had an electric buffer to get the stuff off.

I have been a loyal user of Autogylm for many years...and still buy in volume from my local dealer.

So what do you use?
thanks
