To Paint or Not to Paint?

[gregzz4]

I've always used some kind of waterproof material, such as awning material, or, the most recent, just plain old Fabricland Nylon for $6
It's attached to 4 corners with industrial velcro

If we don't like the black, the wife can come with me and we'll pick whatever shade of blue we want

Only drawback is if you splash water down the back. In your case it would be a permanent mess but maybe it'll give you some ideas ...
