I think they LOOK great there is no doubt but be aware that the life expectancy is a LOT lower than standard rubber. For home use this is probably fine but for operators it would not be a wise move to use them IMO.

I have had a lot of discussions with the industrial chemists from a very professional rubber moulding factory about pinball rubber and initially I wanted to use this type of silicon compound in my machines but from what I have learned the compound will not last anywhere near as well as standard rubber.

Again this is probably fine for home use but I can't supply them in new machines for warranty reasons and potential claim issues.
