It is pretty much useless to write on but I have found many other uses. Toll road tickets, paid parking receipts, ID badges, delivery info or other credentials which must be visible or handy. Or as I intend to use mine by mounting a GPS bracket and maybe a Phone holder to a flat and flexible 8-1/2 x 11 sheet of black ABS plastic which I will heat bend to the contour of the dash. I will clamp this plastic sheet into the van clip board when in use and un-clamp to hide out of sight when parked unattended or transferring to another vehicle. And for those of you who have the same inner-geek as I do........I will countersink from the bottom up and use flat head bolts to secure the mounts to prevent scratches to the dash. I will also use spray adhesive to put some felt or non-slip soft material on the bottom to keep it quiet and guarantee no scratches. If I can find a nice clip board clamp from something in my shop I will drill the rivets out and add that to my flat sheet so I still have the ability to clamp a piece of paper or two. If the single digit temperatures keep up here in Ohio I will have time to tinker with this soon because I am getting too old to deal with this!
