Searching for Non-slip writing surface material

I’m an ID undergrad, working on a final prototype for senior project…This is for a specialized workstation that fits within a moving vehicle.

I’m looking for a surface material to spec, that will have the feel and appearance of a rubberized surface that prevents objects from slipping around on it. However, it must also be suitable as a rigid desktop writing surface. That is to say, it should have the superficial qualities of a rubber mat, but without the squishy thickness that is unsuitable for pressing down with a pen. I’m thinking of some sort of durable spray-on coating, perhaps?..

Any suggestions from experience would be helpful! Thanks.

…try plastisol spray (available in colors or clear at most any retail hardware), aka ‘dip-it’…
