RAM (Radar Absorbing Material) coatings have existed for quite awhile. We use them for all kinds of stuff in the military industrial complex. The main question I have is who is doing upkeep to make sure that material/paint is intact and still maintains efficacy. And also how much is that going to cost? This isn't new tech, but it sounds like some company is trying to market it to people afraid of 5G based entirely on the commentary here.
