Re: Labeling starboard
You'll find it's most common to use a switch panel vs. mounting the switches in the dash by themselves. This facilitates the use of engraving on the panel for switch identification. Some switch panels come pre-labled. Alternatively you could make and id tag from aluminum, plastic, brass, stainless, etc., and have it silk screened with the info you want.
If you don't want to see the screws you can through bolt them with stainless steel flat head screws that are counter sunk and glued into the panel then ground flush and then have the panel powder coated.
Here's a dash panel I did for a friend. I used the through bolt techniqe to hide the mounting screws for the panel. Instead of glue, I Tig welded over the top of the holes and then finish sanded them. The are completely invisible. I forgot to take pictures of the engraved switch panel, sorry.
