It is highly unlikely given the thinness of paint that it has shielding properties that would block DEW at the power densities they are using. See my article on DEW measurement for a sense of the power density used (https://medium.com/@Jay_Coins/in-search-of-the-holy-grail-the-elusive-dew-frequency-b5a947db2a00). For shielding solutions with the properties to block DEW with these power densities, see my article on Shielded Areas (https://medium.com/@Jay_Coins/safe-haven-shielded-areas-and-how-they-can-make-a-targeted-individuals-life-more-livable-809b657a9534). Faraday cage structures as well as 1/8" lead has relevant shielding properties for what TI’s contend with.
