Can confirm it works well. I even found some 1/8 trim plastic (also at Home Depot, don't recall the section, think it was flooring or where they have molding for walls). Slipped right over the edges and cut at an angle for corners it looks pretty professional.

Only downside is I left a DB schema on the board for months and now can't get it off. Probably there is a solvent that would do it but haven't really looked yet. That might be a problem with regular whiteboards also though.
