Hello Jean, Re your question:
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. ... some of the disks have an orange
peel texture, especially at the bottom half of the disk.
There should be a phone number on the label for the company
producing the lacquer. Give them a call and ask for the tech people
or customer assistance. Those folks should understand the best
techniques and parameters for your project.
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.
I would think a higher ambient air temperature would make the finish
dry more quickly. I've tried several spray lacquers, and have only
found one that I'd recommend: G.J. Nikolas and Co. #2105 Clear
Lacquer. It's made for polished silver, so might not be suitable
for copper. You might try their company website for technical help.
Hope this helps,
