I really like the slimness of the GS but dislike the slipperiness. I am thinking that all that's needed is a rubberized coating on the back. I have not such seen such a product before but googling I found that you can get a rubberised aerosol spray from car bodyshops that will give high-build coating.

I'm thinking of masking-off the backplate (to avoid the camera, speaker, etc and the perimeter where it needs to latch on to the rest of the case) and giving it a thin coat. However I am not confident to do this unless I have a spare/replacement backplate, in case I stuff it up. It doesn't look like replacement backplates are available yet. I'm looking for a finish like the rubberized feel on the backplate of the standard My Sky remote.

Any comments as to whether this is a good or bad idea?
