I use synthetic ice. It's a more expensive material but it works great. Just look it up on google and dig around for good prices on it, I don't think it's available at stores.What is the best material to use on the top layer of a snowboard box?
HDPE ( High Density Polyethylene) This is what they use at resorts. Your board won't stick. I haven't found a place that isn't online though. But what you'll want to do is trim the edges with a thin steel strip, so your board won't catch.





but you can order them through these sites, I thought they were pretty decent.
