Superfacial comment

Some 5 years ago I wrote to you asking about merits of dealer offered exterior and interior treatments on a new car. You gave good advice on the use of Autoglym as a DIY alternative and I successfully applied it to two of my family vehicles. On considering the purchase of a new Polo 1.4, the dealer offered Superguard treatment as a superior process to Autoglym on modern solvent-free paint. I found the Autoglym application cloth would become discoloured indicating removal of the outermost paint? Do you have any further comments to make on the matter, please?

Winner of a recent 5th Gear test of paint treatments by Tim Shaw was a £500 professionally applied treatment by . I had still been using Autoglym Super Resin polish, followed by a couple of coats of Autoglym Extra Gloss Protection, but have since graduated to Autogylm High Definition Wax. Wax is different from polish because, while polish cuts away the top layer of paint (as you experienced), wax sits on top of the paint. The disadvantage is you can't wax out marks that you can polish out, so the paint has to be pristine (preferably cleaned with a clay bar) before you apply wax.
