No pics sorry. I am not sure where that board is right now. Trust me though, that stuff will indeed make any soft plastic to have a very smooth "mirror" like finish. Have often used to polish plexi glass. Just used it to blend in/remove a scratch on a very shiny black piece on a very high end automobile. You can try one key and see if you like it. It certainly is not going to ruin it. It is barely abrasive. Like a very light duty polish. So much in fact that it will rarely remove a scratch from automotive paint per it's namesake may suggest. I do recommend to remove the keys to do this. It creates a lot of dust that is going to get into your board. Or easier yet just leave them on, then vacuum the board with a horsehair brush attachment. you can even make the case shiny but that takes a lot of elbow grease. I am telling you this is just abrasive enough to polish smooth soft plastic to a very smooth finish. Not good for much else but at least I found a use for it.
