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
