I have a friend who is a Catfish Guide on Lake Ozark in Missouri. He has a 20' cabin boat and he had the entire inside of the boat sprayed with the Rino Covering. He loves it and the clean up after the day fishing is as easy as just spraying it out. He has a pump on the boat where he can clean his cutting boards as he goes. The bilge pump below deck extracts the water. The footing is not slick and the sound proofing is great. He had the black put in but I think you can get other colors now.
I don't think you would like carpet installed over the covering because I don't know how well the adhesives would work.
