Hi,
I sprayed a layer of varnish on my wp-34s label, which was too matt for my taste, to make it similar to hp keyboards. This is the result.
Now it reflects too much light, but you can try it if you like it so I wanted to share the photos. The label doesn't really look like the calculator plastic.
(I chose a hp-20b becouse it is black, like the label, althought I dont know the difference with the hp-30b; I still need to flash the calculator)
