Thanks for the reply Tez, very useful indeed. I am probably going to order a Kestral DAS6 from a relative who works in that sort of business. I currently use Autoglym Super Resin Polish wich from what I have been told has little to no cut. Someone on Cleanyourcar.co.uk recommended someone else to use DJ Lime & Prime for a light cut, but as I really could use some clarification.
In the same post the guy went on to say he uses DJ L&P, Autoglym SR & then Poorboys Black Hole Glaze, seemed excessive but I'm no expert.
