I guess the question is, after perhaps a few years of being on the keyboard, how easily does the mask come off without leaving sticky residue, or even worse, pulling up the original graphics..?
Adhesives have a nasty habit of changing over long periods, and exposure to sun and heat and moisture. I’d sure want to talk to someone who had had one of these on their keyboard for a few years and then removed it (perhaps to sell).
Very good question Diki, not sure myself. But there is videos on Youtube for the coloured stickon one that shows them removing it off the keyboard; but not after say a few years. I guess if you have a scratched keyboard anyway, this is a great way to dress it up.
Also, if after a few years it gets ratty and not so nice, then remove it. Clean it as they advice ( when putting on the first one) then put on a new one, so it looks a treat again. Then sell the keyboard with the new cover and labels for the new buyer.
For me I would think it you are gigging with the keyboard it will bevery knocked around after a fews years anyway. Unless you are very careful indeed. Also, I have seen a video where someone has repainted a Motif XS keyboard in White paint and then a clear coat. Then replaced all the labels for the buttons and knobs ( from somewhere) - it looked great.
Here is a Korg PA4x painted -
