Wow! I have always had in interest in the RDM but I have heard that they don't flush as deep as the RX. I think you just renewed my interest. Your results are fantastic on what looks to be a tough pub job. Way to go. By the way, what prespray did you use?
I have been a happy RDM user for the past 4 years, we don't do nasty APT's or Chinese restaurants so the RDM is the perfect tool for us, not having steam shooting everywhere keeps the humidity low in the area & keeps the user cool as well.
The testing lab equipment wasn't set up for a rotary machine and the sample kept flipping out of place. Instead of figuring out how to keep the carpet in place they just gave it a lower rating. No appeal, no figure it out and do it over. Any wonder why manufacturers are getting "systems" approved? Because they have some control over the system testing and no control over the equipment testing.
