Roof recoating questions

[Grubmaster]

I have a 2003 Myacht Houseboat. I know it isn't a RV but it's just like a camper except it's on the lake. We spend more money and time at the local RV Dealer than the marina.
The roof doesn't look great (it's not leaking) and I need to re-coat it. It is a rubber type of roof and I don't know if it's a EPDM or not and don't know how to tell the difference. I've been told by the tech person at Kool Seal that 2 coats of their Primer and 2 coats of their Kool Seal Elasto Meric Roof Coating will do the job. They say each product covers 100 sq.foot per gallon. They said not to use the Kool Seal RV product. Does anyone here have experience with their product? I am looking for a latex product and this sounds like it will work. Also I have an account with Sherwin Williams which owns Kool Seal so I should get a better price. The boat is under cover 99% of the time and the roof does get some foot traffic. No shoes, only bare feet and flip flops.
I appreciate any suggestions.

Your houseboat is an RV - recreational vehicle. The only caution I'd bring up is that your roof is meant to be walked on regularly, while a motor home is only walked on for maintenance. I'd check at a marine center and see what they would recommend. It might be a more durable coating made for decks.
