Quoted from DCFAN:Jack just said that the flipper button protectors are not needed because they are using a special coating to protect the cabinet from wear.
This is really interesting...
Last year I've sent them samples of transparent decals which exactly fit around the flipper buttons
to protect this area from wear (made with a cutting plotter). They have nearly zero softeners and a special glue, which makes
them easy to remove and they are less expensive to make, compared to the rails with ears.
Maybe this is the solution JJP has choosen...
