This whiteboard product from Rustoleum looks very similar http://www.rustoleum.com/CBGProduct.asp?pid=128 Note related the blackboard and magnetic paints.

In NZ there is an alternative paint solution, Resene Aquapoxy in Black White, though perhaps not as neat - as it requires a solvent to clean it off. see article NB pdf http://www.resene.co.nz/homeown/habitat/pdf/paintnotpaint.pd...
