Back in 2009 there was a thread talking about product preference, WOW wax by Blendco was mentioned. I will have a year under my belt come April 15 owning my self serve car wash. What products do you prefer? I haven't been in the business long enough to have experimented with many. I do have a presoak that I am sticking with. It is excellent, dissolves bugs on contact, it is made by MarkVII called Bug getter. I have had customers tell me they come to my wash because of the presoak. My competition at the other end of town uses Rain X. I was just wondering if any of you have a product that has worked well for you?
