I used Swissvax 'Blau-Weiss' on my BMW, which is a dark red colour. Today the car has taken on the most incredible gloss and depth of shine. I previously used Collinite 915, and for me it wins hands down. Wish I had a digital camera to post some photos.
Yesterday was my first *real* detail - wash in Megs gold, sonus sfx ultra fine clay, dodo juice lime prime, then a coat of the Swissvax. Really tired afterwards, but today my car looks the best it has ever done, even better than when I bought it new from the dealer.
Swissvax say to stand the car in the sun after waxing and allow at least 3 hours before driving. I did this and as they say, the car took on an even deeper lustre.
I'm a very happy man!
