Flex Seal spray works great

I can't say enough good things about Flex Seal products. I swear MacGuyver would be proud of me when I get any of their products in my hands. There's nothing easier to use than the spray just might want to use the paint on if you're using it indoors. The Flex Seal products are 100% waterproof and they perform as advertised. BUY THIS! IT DOES WORK

Walmart for the win

I bought a can at the HD store and used it on a 4' x 4' shed roof. The trouble was it only covered half of the piece of plywood. So I bought another at Walmart for less money. It covered the entire panel and there was still some left. All I can guess is that the HD can was so old it had lost its aerosol propellant. It's expensive but a lot less than any other casual roof protector. Its working too protecting the bare wood.
