Why use paint at all? Why not just just use calcium carbonate (lime or even hard water scale), which is also just trapped carbon. It's white enough to do the job and should be cheap enough to make or dig out of the ground or have marine critters make them for you. Might have to reapply once in a while due to acid rain and stuff though.

who are too f*cking cheap, too uppity for worrying the look of their house ruined by a satellite dish, and too stupid to just hide the dish in the 300-yo attic can kiss my a55. These are probably the same a55h0les that blocked the wind farm off of Nantucket sound because, oh no, it'd ruin their view. They deserve to live without the internet.
