Re: Rf shielding paint
Foil is actually easier than paint.
The paint is thick, messy, dries slowly and takes many coats to be effective. And even then I do not believe it produces a better cage than copper foil at all. The shielding paint just does a poor job, and it breaks down over time rather quickly.
The foil on the other hand is clean, very effective and nearly fool proof. Add in the fact that it is faster by about a factor of six and there is really no choice between the two. Even if the adhesive fails after years you are still left with a fully functioning faraday cage, something that can not be said for the paint.
It also costs about 4xs more in materials to shield with the inferior paint.
