My rf tuners came with a special coating over the aluminum chasis that kind of gave it a gold appearance.  Then I'd seal the corners with a conductive tape made by 3M.  That coating was a spray-on, never bought any.  It was for rf-radiation reflection.  Not really a paint though it was applied like one.  I saw it done at the factory.  Sometimes they referred to it as gold anodizing, but it wasn't done in a vat.

    Spray on galvanization says that the metal particles do make
    conduct as it is drying.  Otherwise the galvanic action would not
    occur.  Seems hard to believe but it seems to work.  I used nickel
    loaded paint for an RF shield on a plastic bezel once.  It was
    very conductive. Easy to measure with an ohmmeter.  Very expensive
    too.

    Mexichrome will flake off at times and has a foil like constancy.

    It’s been 50 years since I took field theory classes, and even at
    the time I didn’t do so well in them.  Maybe Chuck can keep me
    honest here.

    But I seem to remember something about a shield being effective
    because the entire surface was at the same potential, and also
    something about currents need to be able to flow to counteract the
    magnetic field.  Bottom line being your painted surface would need
    to be conductive, not just paint with individual metallic
    particles.  I don’t think it’s necessary that it be grounded, but
    you’d want to be able to connect a continuity tester at 2 points
    on the wall and have it beep.

    I do remember at one company I worked for we put in a conductive
    tile floor in the lab, that actually was grounded.  And the
    cleaning crew had to be told not to wax it, or use a special
    conductive wax.  But that’s for ESD, not RF shielding.  I worked
    for another company that made TVs, and we had a bunch of small
    “screen rooms” to work on equipment.  But those were made of
    copper screen.

    Demo would just be painted panels, production would be permanent.

    Looking for a product like this is a crazy rabbit hole. You catch
    one thread, thinking it will point you toward a product and it
    sucks you in. You think to yourself, "self, they cant really be
    this retarded can they?" Self says "Read on my son" and you do.
    And holy cow, every layer they get more inbred. Next thing you
    know, youre 4 hours into reddit and starting to think, yes, maybe
    that smart meter is why i feel like shit all the time, its
    definetly got nothing to do with the quarter stick of butter i put
    on those 2 porkchops at midnight last night or the 30 plus years
    of non stop drinking and 1-3 packs a day, its definetly
    commonwealth edison and their conspiracy with big solar to make me
    sterile So I can be a manchurian candidate assassin for the cabal
    under the pizza joint. You start questioning every decision in
    life, were they your own? did the RF illuminati control it? Is
    everything I do because of the tumors in my brain i dont know i
    have yet because my neighbor talks too much on their phone? Should
    i kill them in self defense? Is my dog being quiet because shes
    keeping secrets?

    And I still dont have the product im looking for

        You would have to top coat it with something that looks OK.

        this would be in public view, needs to be normal looking
        paint. you have any product names for legit product that
        doesnt come from the bat shit nutters in the 5g death ray camp

            Zinc arc spray is great but takes a machine to do.

            Aluminum foil and spray glue.

            So, for a project to block cellular signal in some rooms I
            started looking for a paint that will filter/ block,
            faraday paint if you will. We want to force all cellular
            users to move over to wifi calling in the locations for a
            wifi marketing product demo

            It quickly becomes apparent that gets into the batshit
            pool of crazy with EMF blockers, etc

            Is there a brand/product for this purpose that works well?
            Paint is always an option, copper mesh is not
