Mike, welcome to the forum. I moved your post to its own thread here, because I think you'll get better responses. I know nothing about rubber roofs, but many members have that kind, so someone will be along to help you.
We’re just finishing up with our 33’ reroof. We went with crazy seal it has lifetime warranty. We’re putting the roll on coat today with final coat following. So far excellent adhesion & seems super rugged. We had to remove the aluminum roof in places to replace 1/8” plywood. We ended up purchasing 2 kits price was $1,800.
