Anyone try one of those roll on products to make concrete smoother for shooting or dryland training? I'm looking to setup a shooting area in the garage for my son and want to extend it to the concrete outside of the garage. I bought roller hockey rink tiles for the garage and they work great (even for ice pucks), but that's not practical for outside because cars will park on it. I've seen really slick/smooth concrete in industrial buildings that a puck would slide nice on. That would an option, but I figure it would be cheaper to just put a coating of some sort on the concrete like they do at outdoor inline hockey rinks. This would be for stickhandling and shooting not inline skating on.
I'm looking for a product like this: http://www.sportmaster.net/skating
Anyone try something like this? Results? Recommend a product?
