I did a little experiment yesterday - took some "Press n Seal" (the new Saran Wrap type product) and covered my Smart Key with it. Because the stuff acts kinda works like tiny little suction cup it seems (so far anyway) stick pretty well. It takes a little time but for those of you who are fairly handy I think you found your answer to the "easily scratched" Smart Key surface. Take a look at the pictures I posted in the Share section.

 

Did you take the remote apart to put the film on it? You did a very nice job. I will have to try this...

 

no need to take the remote apart. just grab a piece of the PnS and wrap it.
