I know Vivid Lamination do a dry-wipe laminate.
We’ve done a similar thing in the past using self-adhesive magentic roll (we got ours from Pyramid Display)… use something like a big sheet of mdf or alupanel cut to whatever size board you need. Stick the self-adhesive magentic roll to it. Print on to vinyl and stick that on top of the magnetic roll. Then laminate all that with the dry-wipe laminate.
Worked for us although their are quite a few processes involved so there may be an easier way.
