The bedliner took two coats to make even, so not too bad there. Point of advice, spray multiple directions, i.e. across, up/down, diagnal, circle...
There is really not that much land between the spots, but I left room for "expansion". I plan on (in the future) to add Drink holders on the sides (thats why there is 4" overhand on the sides), and a trackball will go in the middle eventually (read as: when I get the money), possibly a spinner. But I also added space between area's so there is room to lean on (not just old people
) Also, I wanted a nice overhang so that the hinges (not installed yet) are hidden well.
Currently the board stays together with two strips of velcro... Holds actually quite well, doesnt slide around at all...
Heres a picture of the wiring and the velcro...
