Quoted from Rdoyle1978:I don’t know exactly, but you need to let each layer really cure for about 30 days, and if you do several layers .. Doing the math, it’s probably not practical at the pace Stern is going. I think they spray them, let them cure enough to not be sticky and then do the next layer, etc. This means they are still soft underneath, and still malleable, so the ball pushes right through to the wood, and there you go, a dimple. If we were to not play our NIB games for 6 months, I wonder if the dimples would be far fewer, as the clear would have had time to cure.
This would be easy to test if you find a dealer that has a game that's been sitting at their warehouse for a while. Finally get some use out of the WWEs!
