I've used a local sign shop for vinyl transfer lettering for contest ID and registrations. Very simple to apply – lots of options.

Instrument panel labels are of course a much smaller font. Check with the sign shop.

Vinyl lettering is great for large lettering (1/2" minimum and above, *MAYBE* 1/4"). But the very small lettering you might use on a panel is almost impossible getting the letters to release from the transfer tape and onto the panel without loosing a few in the process. Been there, done that.
