Using
a Laser Cutter on my CNC to cut the yellow Tamiya Masking Tape stuck on a plate of Glass is how I made the Spray Masks for my King Tiger ( the 204 ) , Pershing ( the Star ) and E-100 ( the 404 & Cross ).
Works quite well for stuff of that size but anything much smaller like the serial lettering on the Pershing will be too small too comfortable work with as the Masking Tape does have a tendency to be "fuzzy" around the cutting edges 🤔
The heat of the Laser will also weaken the glue as will the reapplication from one surface to another soo... yea. It may work for you and it may not 😉
