I have always used Swissol products on all my cars. Comes up with the best results.
I went for the teflon kit (think it was about £150) Includes everything from claybar to cleanser, shampoo, wax, cloths etc. Well worth it in my opinion and im sure many other people will also recommend this product.
Give Paul a bell on Performance Parts 4 U 07968 842103 and tell him Bobby sent you to get current price of kit or individual items
