    In a previous life, I painted various enamels and lacquers, and if
    you are working from a spray can, 12 inches is too far away to have
    proper "mixing" of the paint in the air before it hits the prepared
    surface.  I found that 8-10 inches away with most spray paint is
    about as far away as can work effectively.  Also with the solvents
    present in the plasti-kote paints it will help if the actual object
    is on the higher end of the temperature range.  I once worked with an
    epoxy type of paint that required 100 degrees to "tack" in ten
    minutes, or at 65-70 degrees about 36 hours to the "tack" stage. 
    (tack is the stage where all of the active solvents are gone from the
    surface, and the pigments are left to cure. Also with a lacquer, you
    may be able to re-coat the discs with the paint and remove the orange
    peel surface.  also if hanging, it will allow the solvent loaded
    paint to slide right off of the surface, building up on the lower
    edge, so if you could paint flat, it would probably improve what you
    are trying to do..
