DUH! So this is like Dow Corning All Gard, which competes against acrylic elastomeric coatings. Only problem I see with that approach is that once coated with silicone, nothing else is likely to be able to adhere for recoating.

As for EIFS, most of these systems are little more than highly sanded acrylic latex paint, and the same repair can be done with acrylic elastomerics. That preserves the potential to recoat eventually, for whichever EIFS buildings aren't going to be demolished before the paint job wears out.
