William...Just got back from meeting with the Auto Magic salesman. Supposed to meet him at a body shop across town. When I got there he had just left...said over the phone that the stuff costs 17.00 a gallon. I asked the body shop people if they had ever bought any alum cleaner from this guy and they went and got two kinds, one in a spray bottle marked "do not use" but it was non acid based "Auto Magic" on the label and a gallon of "Spoke #66", acid base. I asked if I could try it and got a bucket of water. It seems to work pretty good. I asked if I could get some in a small bottle and they gave me both and said I could have them, a gallon of the acid and a large spray bottle of the Auto Magic. BTW the first guy I called (truck detailer)was real nice but said he would not sell me any or give me any. I guess he thought I was a terrorist or a lawyer. He turned me on the to the Auto Magic guy. I will report back after I have had a chance to try this stuff out. I found a great web site for cleaning aluminum, posted by a motorcycle guy who has researched all the methods, you might want to check it out.....www.team.net/sol/tech/clean_al.html. William...thanks so much for your input and all the rest of you guys. This research keeps the juices flowing and I appreciate your help. I will get back to this tomorrow Dave
