Is it bad to wax your playfield often? I am not talking about polishing with Novus 2, but just wiping the playfield clean with a microfiber cloth and then applying pure carnuba wax. I love a freshly waxed playfield (on my Diamond Plated and Non-Diamond Plated, so wax every several months (no less than 2 months, usually no more than 4 months), but is there a downside to this? Will the wax and/or my applying it (rubbing) impact the insert decals? Am I better off cutting the waxing down to every 6 months, or even just once a year? Thanks.
