I pick up my new A3 on Sunday and having not paid for Lifeshine, I thought I would do it myself. I have an old Lifeshine pack and have bought extra's from AG but I decided on a wim to go out and buy the HD Wax rather than use the Extra Gloss Protection that I have been using on my old Astra. Anyone had any experiences with HD Wax? Any tips? I'm hoping it will give my Daytona Grey and extra pop.
