I did this to my Skateball and LOVE IT!!!! I also had many potholes (sunken inserts) that would affect ball trajectory. The only issue I have now is occasionally the ball will hang up on the lip of the protector by a star rollover on the upper left by the flipper if the ball is not moving with much speed. Other than that, it's like a whole new game. Bringing it to EXPO in a couple weeks for all to enjoy. Cheers, RD!
