Has anyone tried one of these coatings for extending the life of an EPDM rubber roof? If so, how well does it work?

We have an older 5th wheel on which the roof is showing fine "spiderweb" looking cracks. Getting close to end of life. Would like to continue using this RV for a couple more years. I found these two products that look like they are intended for this purpose.

FWIW, I only knew about the Dicor kit. It is a bit of a P.I.T.A. to apply but once done, it only needs a re-coat every few years.

It is a two part deal. After you wash and dry the roof (after taking off all AC and vent covers and sealing any cracks with their self-leveling sealant), you apply a special adhesive primer (in sections unless you are working off of scafolding or ladders from the sides) and then shortly after the top coat.

I believe you use brushes and rollers to accomplish this process. It basically adds another breathable layer of rubber to the roof and is supposed to create a bond like concrete re: strength while still remaining flexible.

I think the 30' MH kit runs around $500 and then you buy more primer and top coat for longer coaches (like ours... ).

I know nothing about the other but if it is a one part (like Cool-Seal), you just have to thoroughly clean and dry the roof. I have used Cool-Seal and it works O.K.

A replacement rubber roof install runs around $5,000 or so for a 40 ft. long coach if my memmory serves me correctly and it "should" be done in a controlled, covered environment unless you have really good weather and no dust or bugs.

Just my $.02 again.

Look at Elixir Industries Plas-T-Cote Rubber Roof Coating. It is a one step cover. I works GREAT. I have used it with good success.
