Good day, Since I now have a new one in my row, I want to prepare for the first time myself. Before that I always had everything done, therefore this beginner question… The Benz is a w124 color according to papers gray (photo attached). He has a nice varnish. Only here and there some marks. Scratches as good as none. I have read many posts and also some good tips. However, the question, hand or machine (both available 😛 ) arises to me, which polish? After that wi e seal… wax?… Unfortunately I did not find a thread directly, especially to the varnish. I ask for help! Lg
