definitely use a label maker for a clean appearance if you're going through all the trouble already.
==============
As to label making, I have used these guys to make engraved placards for my panel work. Their stuff is 1) inexpensive, 2) very professional looking, 3) they stay stuck! I make up my simple designs/requirements in PowerPoint with notes on size, color, etc. Be sure to order a few with your tail number for the panel - you will find other uses for them.
