    ok, so i finally tried the liquid mask experiment last night. i used this stuff (i think):



    results: total failure.

    experiment 1: flow and demask. by the time the powder flowed out, the mask was liquified.

    experiment 2: full cure and demask. the liquified mask outgassed so violently that it sputtered onto the clean sections, and it cured into the powder and adhered to the part.

    on the bright side, for wet paint it did work well for masking some chrome that i couldn't find tape that would stick to. it took a long time to dry, like 24hr.

    I have wondered that at times. I also do the "flow and de-tape" trick. Got to try it one day when I remember Damn old age LOL

    Could you use it to mask, put the part in the oven until just before the powder starts to flow (a minute or two). Then pull it out to remove the mask and back in for full cure. (same thing that I do with the tape, you get a much cleaner line).

    it'd be interesting for sure to see if it works.

    i have a project i'll be working on in the near future that will require weld beads to be a different color than the members they join (the polished aluminum beads will not be coated), and i would expect trouble from the irregularity of the surface if i used a tape or adhesive type mask. at the moment, i think the wet sponge paint brush technique to remove the powder after application might be the best shot. i expect that to take much more time than applying a liquid mask, though.
