So that thread didn't actually run its course but it gives some thoughts to how to approach this.

As with any reflection shader, you want to use a Reflect node, modulated by the Fresnel_Blend to get it to behave like real life.

You would do well to have some sort of scratch texture image to help with the surface realism. Depending on which image you choose, I'd blend it in with the rink paint image using possibly different techniques.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
