So, I want to cover my boards (4' on one end and 4' on the sides - think U shaped.

My liner will go over the sides of the 2x12" on three sides, so they'll be 'covered' and snow will but against it (supposed to get 2" tonite).

The issue is that 4' plywood. I didn't get a chance to paint them white before I installed, so it's a huge eyesore. I'd like them to be a nice solid white and they'll blend in with snow.

So, I thought 'wrap'. IronSleek offers board wrap but it's expensive. I thought about basic Tyvek HouseWrap (it's solid white on one side) - but all you can get are 150' rolls for like $150.

Googled 'white plastic sheeting' - maybe this stuff? Rink liners are 6m - this stuff is 5.5m. Black one side, white the other. 10x25 which would do the trick.

Anyone else do anything like this?

I would think that anything you put there is going to get ripped (skates, sticks, helmets, pucks, etc) and will be just as much of an eyesore as the plywood, which I don't see as an eyesore in the first place. Are you planning on doing both sides of the boards because if not, the back side is going to be an "eyesore" if you are standing outside the rink. :-)

You can always paint it later on during a nice winter day.
