Theres a lot of hocus pocus talked about car waxes, after years of using Autoglym and Turtle wax I was convinced by BS marketing that a ZYmol kit was what was needed. 250 quid later I had a black plastic breif case with some sponges and waxes. It had its chance and is still in the garage.
Then I found Meguaires.
NXT polish. Preceded by the clay bar to remove surface oxidation, tree sap etc.
A duster slides off the bonnet and it looks like a new car (its 1997) and it takes no more than 2 to 3 hours.
Total cost less than 25 quid. Including new dusters.
Zymol is marketing over substance for the price of a pair of rear tyres.
Figure it out.
