Hey guys. I'm looking at switching to a new car soap. I usually use the two bucket system, but recently bought a foam lance that I'll use from time to time. I'm looking for a soap that will work with both. I've heard great things about Duragloss and Optimum Car Wash. I want something that will be gentle on the Dodo Juice Supernatural wax that I have on my car. I'm leaning towards the Duragloss. Anyone have a preference? Thanks!
