I've been working with Wolfgang Uber Rinseless for a month and it's been absolutely fantastic. It leaves the surface feeling incredibly slick, it smells great, and the dilution rate is one of the best: 1oz per 3 gallons of water for rinseless, 1:48 dilution for waterless solution. I haven't had any trouble with rinseless or waterless use. It does seem to leave behind a noticeable presence on the paint. If I have a fresh application of Brilliant Shine Detailer that beads water at a maximum level, the waterless ratio of Uber will alter that behavior down slightly, whereas with Meg's Deep Crystal soap I don't notice any water behavior change after rinsing. BSD also feels much slicker afterwards using Uber. Still repels water at a very high level, but with the extreme (and possibly unique) example of BSD I can see a slight effect after the rinse. I'll have to get a hold of some D114 to do a comparison. Overall I jumped on Uber Rinseless when it was on sale and I'm very happy with its performance and dilution rates.
