DYI EPDM Roof coating products

I have found a product call KoolSeal (Walmart) I need to recoat my EPDM roof on my 5th wheel and was told this product is just as good as the costly products out there. ($95/4.75 GL). I am not a wealthy person so the $2000 job at the dealers is out. Please comments are needed from others that may have used alternate products, I know I am not recreating the wheel here..

The stuff sold on this site seems like it might be an option to consider:

Only a thought... I assume the cool seal is some form of petroleum... not good for rubber roofs

When we had a rubber roof, this is what we used:

It's pretty much the best out there and I simply would not consider using anything BIT Dicor on the roof of my RV.

BTW, all rubber roof coatings require 2 coats, so you will need coverage for twice the SQ Footage of your Roof

Just curious, what situation would occur that you would want to coat over your EPDM membrane? I've had the membrane delaminate from the sub base and was able to glue it back down. I have sealed any joints and openings using Dicor color matched sealant. Any tears I used EPDM repair tape. What is the advantage of coating the whole thing? Is it just a stop gap measure for roof replacement?
On a side note you would definitely want to be sure the membrane has not delaminated before you put this stuff on.

DO NOT use Kool Seal, it has agents in it that will eat thru your rubber roof. Look on line or follow the link BamaBob sent you for coating to put on rubber roofs. Been there done that and paid for it, don't use Kool Seal.

I finally settled on using RoofMate HT. I just purchased one of the repair kits from How to repair a RV roof . I called to ask a few specific questions about my repair and both times I called I was able to get my questions answered with good customer service. The have some comprehensive instructions on their site for different types of repairs, prep and different products to use. I received my order in less than a week but I am in CA and I think they are in AZ.
