I have a 2005 5th wheel and the EPDM roof is in OK condition. Looking chalky as normal but still just looking like its wearing faster than I'd like. And I really dont feel like having to spend $600-$800 for a new rubber roof if I can prevent it from wearing out as fast.
I think you've answered your own question - roof doesn't require repairs yet. When it will, then you will do it. "Wearing faster than I'd like" - yeah, well, you're probably also aging faster than you would like, so what? :)
$600-800 about covers the cost of materials only - membrane or liquid stuff. There are 2 liquid coats commonly used, Liquid Rubber and Liquid Roof:
http://www.epdmcoatings.com/. Same stuff, one is more expensive than other. You'll find it on Amazon as well. One gallon covers about 40 sq.ft. In comparison, Superflex linked in earlier posts covers 1 gal/200 sq.ft, so this sounds pretty much like paint.
Liquid Rubber is a "restoration" and is done when it has to be done. Until then, most people don't do anything other than careful washing (optional, IMO) and/or sprinkling UV protectant like 303. Sorry, don't know any super-wax that would cover it and thus stop it from deteriorating completely. Some people try this or that magic goo, most don't, and there is no evidence that it makes a difference. If such thing existed, we wouldn't hear about membrane replacement or restoration.
