Well a consistent vote for Auto Glym, and I have to agree. I've been using their range for years now and they are fantastic and great value for money.
Some of the products like the bumper stuff has lasted me over 5 yrs. In fact for my new MINI I stocked up on the whole range cost a small fortune but the car just cry's to be cared for.
My advise to anyone would be to check out their great Web site.

Use the list top right and read their detailed advise on how to really care for your car.
