I'm not sure when the car was supaguarded. The car is second hand on a 53 plate so I'm assuming it was supaguarded when new, so from what you say below, I should probably start from scratch. That said, it still cleans really nicely.
The products I use include:
Mers car shampoo
Autoglym super resin polish (never used on the Golf yet)
I will have to buy a new wax as my old wax was for use specifically with dark colours.
What wax would you recommend on a silver car for a long lasting deep shine? How about the new Autoglym HD wax?
What sealant would you recommend - is Autoglym Extra Gloss protection any good?
In case you haven't already guessed, I like the Autoglym range of products
