I seriously doubt Rockwood uses Proflex. I don't know of any manufacturers that do. Probably too expensive, and too good. I've used it for years, and practically go over every factory seam with the proflex once I get a new RV home. It does stick to just about anything, and is by far superior to anything I've ever experimented with. I wouldn't sweat what's on it. I'd be confident in going over it with Proflex. On the roof, I prefer covering all factory sealant with liquid roof, as ours was done at the dealer. This is my first RV with the liquid roof done like this, and it holds up way better than the dicor. Just clean really well and paint it on over the dicor. It's something our dealer does just because it lasts so much longer. If not comfortable with that, just dicor is fine. Just my 2 cents.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
