I should be a martial arts master after washing, wiping, and waxing my Airstream. At the very least, my fitness oriented wife is pleased that by helping wax the Grey Whale (our Airstream) her arms got a toning workout. It's not hard work, just time, attention to detail, and the right products are required.
If you are an Airstream owner, you can go from spots to a shiny reflection if you wash and wax once or twice a year. It is painstakingly slow, but worth the work. (You can also call me and I will do it for you. It's a great way to stay warm in the winter.)
Walbernize RV Super Seal polishes, cleans, and makes the surface waterproof. You can purchase it directly from the Walbernize website.
