Acrylic or Silicone to coat EPDM roof?

[Olyteddy]

Has anyone used Henry 887 Tropicool ( StackPath )on a 24 year old EPDM roof? Currently all seams are caulked with Dicor type sealants. They also make a Urethane enhanced Acrylic ( StackPath ) that looks more compatible with older roofs. However I have been unable to find the type 817 product. Any other product recommendation is of course welcome.

6 years ago I coated my roof (1996 Fleetwood Storm) with the Henry 887. It still looks new today.

What was your prep work?

Follow up: I am able to get the Acrylic type 817 through the pro desk at Home Depot.

Why do you want to use Henry 817 when Henry specifically recommends against it for RV roofs? The quote below is from a Q&A and answered by a rep of the Henry company

A: Victor, we would not recommend Henry 817 for the application to RVs, Campers, Trailers or Motorhomes. The only coating that we recommend for camping vehicles is Henry 887 TropiCool 100% Silicone roof coating because Henry 887 has a 280% Elongation rate and can withstand the racking and distortion on vehicles traveling on the road. Henry 887 applies in a single coat, is waterproof and has a lifetime warranty.
