I've sprayed the Zinser Amber several times. Works very will if you tune up the gun settings and N/N set.
Lowest temp I've sprayed (more or less) is maybe 55F. Highest was probably over 90F. More trouble at higher temps. I used turpentine as a retarder for the higher temps. No change for lower but it may take a bit longer to dry sufficiently for de-nibbing. Don't have my notes here but it is likely I diluted it just a bit to come down from the 3# cut in the can to something more like 2#. More light coats works better for me than one or two heavy coats.

I regularly spray SealCoat (Zinsser's wax-free shellac). I don't want to contaminate my HVLP gun, so I use one of the cheap Harbor Freight sprayers off a compressor. I think I would recommend this instead of the waxed Bullseye. If you ever decide to top coat with something else, you could have problemes with the Bullseye.
From Bullseye product data sheet:
Application Conditions Warmer temperatures will accelerate and colder temperatures will prolong the dry time of this product. Do not apply when RH is greater than 85% or when temperature is within 10º of the dew point. Bulls Eye Shellac is not recommended for use in areas where surface heat exceeds 160ºF (71ºC). (Note – If in doubt, always test apply shellac on scrap wood before using).
From Seal Coat product data sheet:
APPLICATION Apply only when air, material, and surface temperatures are between 50-90ºF (10-32ºC) and the relative humidity is below 85%.

I spray shellac fairly often. I've sprayed outside when the temp was about 32. Took a little longer to dry, but otherwise no problems. Humidity is the real concern. Conditions need to be dry.
Be sure to check the color on a piece of scrap. Amber shellac, straight out of the can, may be darker than you intended. If you just want a subtle amber tint, then go with the clear shellac.

I pre-painted my wainscotting and only needed to fill the nail holes after installation. I pre-cut to height the pieces of plywood. There were a few trim cuts and a small amount of touch up but much easier than painting in place.

I think I am going to go with the clear seal coat. The Amber was to orange after 3 coats on my sample.
It's going to cold next weekend when I spray but garage will be toasty.
I will post pics when it's all done.

Here one panel of 8 total. I really like the color and the fact that I didn't have to stain them too. Had to get creative on where to let all the sheets dry in a two car garage space.
Next up, cross cut to 4 ft and begin surfacing and milling all of the hardwood lumber.
