I just ordered 6 gallons of the EPDM RV Roof coating and plan on coating mine next weekend. I've been planning on doing this since I got the RV three years ago. I've read a lot of different articles and watched videos o how to do it, . The one coat system from EPDM Coatings seems like a good way to go.
I'll get the roof ready this weekend, replace the A/C seal, remove the old original satellite dish and patch the hole, remove the Maxx vent covers, and clean and inspect the roof.
I believe the roof is original, its in good shape with no leaks, but it is chalking and probably overdue for maintenance.
This is the stuff I ordered:
