I didn't know that InvisibleSheild made these, but they are awesome.
I have one for my Ipod Touch, and love it. It has protected my precious Ipod from soooo many scratches, and they can protect your gauges too.
I also have one for my GPS, and it protects from water damage!
(Which I hope wouldn't be a problem with a gauge or computer)
