Has anyone used R-28 paint?
I heard there's a paint that has R-28 insulation value. Not a lot, but a lot for just paint. Anyone used this? Any observations?

R-28 paint would be a miracle. A 4" thick wall can only get up to R-13 with fiberglass insulation. I've never even heard of paint being considered for its insulating value.
