Here's one for you - a good insight as to what a pre-wax cleanser has to offer if used to its utmost! BMW 650i Cabriolet Enhancement and Protection with LTT Interior Detail I first saw this car ~2 week ago whilst working on the Mercedes GL420.. Ever since, Ive been looking forward to this day. You dont see many 6-series on the roads.. They hold so much road presence. I like!

Interior inspection: Cream carpets! eek!! In making sure I dont end up tripping over myself, I set up base: I first tackled the wheels. A mix of G101 and Wheel Brightener used to clean the alloys, tyres and arches. Claying was required to shift a healthy pitting build-up. Moving on to the roof, 303 convertible hood cleaner used here later protected with x2 coats of Fabric Guard. Snowfoamed and hidden away areas were worked with a brush or two. Washed in the usual manor. Two buckets, washmit, Dodo BTBM. Finally, Sonus Green Mild clay used to lift surface contaminants.
