    i have just sprayed some 1 1/2 inch pierced copper disks with
    plasti-kote hi-performance classic fast dry lacquer (no. 349) with
    less than perfect results.  the can says that air temperature at
    application should be between 60 and 80 degrees fahrenheit.  propane
    is used as a pressurizing agent. 

    some of the disks have an orange peel texture, especially at the
    bottom half of the disk.  

    i prepared the disks by burnishing them in steel shot for about 10
    minutes, washing them with water and a little liquid dish washing
    liquid, patting them dry and then shooting them with a hair dryer.  i
    applied the lacquer by hanging the disks from a cardboard "spray
    booth" in the detached garage, giving the disks a couple of shots of
    well-shaken lacquer from perhaps a little more than 12 inches away. 
    i was really conscious of getting far enough away and applying only a
    small amount because my first try caused runs.  i did this in the
    garage that i had heated to a little above 60 degrees fahrenheit.  it
    looked as though all the disks started out with the orange peel,
    spotty or dotty surface right after spraying and then the lacquer
    spread out to make a smooth surface (sometimes). 

    what do you think caused the orange peel lacquer?  i'm leaning
    toward temperature, thinking that a higher temperature would allow
    the lacquer to spread out a little more before it drys.  

    what has been your experience? 

    as always, thank you for your time, wisdom, and kindness, jean adkins
