Just to share my experience. I have an RV rental fleet and I have tried every type of roofing material known to man. I have redone at least 25 roofs (EPDM or TPO) with all sorts of products, from the ones designed specifically for the application and the ones designed for other applications. For example, I have used Thorugh-the-roof, which is the best roofing materials for transparent surfaces, like the skylight. So far the best I used was the materials basen on Polyurea (truck bedliner stuff, like Rhino-liner).
The last one I tried has proven better and has become my new favorite. US Coatings RV Roof 100% high solids silicone. 2 layer application and the result is incredible. I saw the material at work and it looked great for the roof a one of our buildings, so i asked them about RV applications and they told me they have a kit with what I need that is developed for EPDM and TPO. I tried on one of my small fleet RVs and it worked great. In theory, it is a 20 year warranty material, and after working with it, I believe it.
I am getting ready to do my Alfa next, I'll document and post.
I got it from US Commercial Coatings in Florida (1-800-779-0821). I even believe they can do the application. I saw what they did at the plant and they worked great.
Needless to say, I have no commercial affiliations with them.
Hope it helps.
