I used your cleaner 1;5 ratio. Pressure washed good. Next afternoon flash coated. Next day coated roof. I put in thick to get the amount specified used. 40’ fifth wheel. Big bubbles. I got on ladder and pressed on some and it’s like the thick liquid roof but it didn’t adhere to the flash coating. Hope it’s not like what the rv dealer said the reason they stopped coating roofs is people come back saying it blew off going down road. Also I have2 of the 8 gallons left.
