When custom painting and lettering an engine, what is the best process to use for the number boards? Since the number boards are lighted, I have tried using a black decal film over the number board and then applied white numbers. However, the black decal does very little to block out the light.
I've also used my office jet printer, to print a black area with white numbers. This looks better than the black decal approach.
Anyone come up with a way of blocking out the light, short of unplugging it.
