Epoxy is fine, usually forgiving too. The reason I use oil base is that it is extremely durable, and goes on in a layer that is very thick (several Mils over regular paint) and is also forgiving and most of all cheap!
My overlays are complicated to explain without a few pix, but I'll try.
First, you need a really good laserjet printer. You also need matte finish photographic paper, and plenty of black ink. Dont forget the thin plexi from Hobby Lobby
if yo are getting a 1-2 season car, you will need to use a jpeg capable program (not paint) and first experiment with simple black borders to get the overlay sizes right (please remember, this is the tight budget method).
Once you have nailed down your sizes and parameters, drawn all of the graphics in , then you flood fill all the right places with ink.
Mine is a fourth season, so all I needed was the white-on-black lettering on a piece of matte photo paper, and cut out the words. I put a layer of thin plexi over the board, and where my LEDs are I masked with tape cut to cover the leds, then painted with semi [not satin] finish, black. Then I removed the tape, and viola, a cover ready for labels. Using double sided scotch tape, I put the cut out word on a piece of tape, trimmed of the excess tape, and applied where needed.
For you, you wont need the paint, but you will need to get your overlay sized right, and I mean right.
Do your masking for your readouts and LEDs, replace the paint with spray adhesive, and apply. Don't remove the tape, yet. Apply your photo paper as you would a decal, from one side to the other, with a decal squeegee. Work the paper well into the masking tape strips, you will need the definition for guides. Let the setup dry for a few minutes, and peel a few razor blades. Take a brand new SHARP razor, )not an Exacto, they don't work) and carefully cut around the edges of the masking tape. If you do this right, just the tape will come up with the photographic paper attached to it.
If you do the whole process right, you will be able to place the plexi-now-overlay over the circuitboard, and go WOW!
I have to go to bed now, I'll get back to you with a surefire safe method of mounting these to the boards, and the whole assembly to the dash.
