I want to engrave a design into a piece of white board (basic home depot MDF with whiteboard finish). I have a test piece cut and I marked in the engraving with black oil marker. I’d like to leave the masking on it and put some sort of finish on the engraved/markered area so that someone could use a dry erase marker on it and not make a mess of the black engraved area. not necessarily for heavy use, but to at least be able to do it more than a few times w/o totally messing up the black.
thoughts on what finish would work best? I probably get one shot at this and have to do it tonight after work.
