Boat Flooring

[muttmechanic]

Hey guys,
I have an aluminum boat Ive been working on and it has an aluminum diamond plate floor in it. I want to put a coating on the floor so that if we are on it barefoot it won't scald our feet. I don't want to put carpet down. I was just wondering if there would be some type of coating like bed liner that would insulate the aluminum enough that it would help. I know white would also probably help make a difference but it is going to be a hunting boat in the fall so I would need to stay darker. The only thing I have been able to find so far is the hydroturf that gatortrax offers. Thanks for any help you can offer.
