Listen dude, no matter from what company you buy the LED board, keycaps will give up on you really fast. These type of coating wont hold, the only company that has durable/Industrial keycaps for LED keyboards is TG3 AKA deck... Those caps are mix of PBT outer shell, ABS see trough inner shell and legends are dyesub in a way to accommodate light going trough the cap... I might be wrong but I think SP makes these keycaps for TG3 and Deck.
