I applied Hydro Blue Pro HBP all around my 37' motorhome. I watched a couple of videos, but I wish there were better instructions as to the application rate and the volume of water necessary to rinse/distribute the HBP. I applied HBP over a 2-day period, to keep out of the sun. It was windy, and as I sprayed HBP onto motorhome, the wind blew much product away from my immediate work area. Maybe this is why I used nearly 2 quarts of product. I also used a garden hose to rinse rather than a pressure washer. Still, I'm satisfied with the product and you won't find anything easier to apply! We'll see how it holds up, but I'm expecting at least a year, as my motorhome is stored indoors, so routine weathering shouldn't hasten the need to re-apply.
Pros:Easy to use recommend avoiding windy days
Cons:Inadequate detail as to how much product I should anticipate using, and better instructions as to rinsing.
