Re: Any one know were i can get grip tape or a rubber pad??
3M makes an anti-skid product, can't remember the exact name at the moment, but it works wonders. It is what the USCG mandated that we use on the rescue-purpose airboats we built for them. Take a little bit and look at 3M's online catalog to see what they offer, as I know there's actually more than one product, depending on application.
I would shy away from using truck-bed liner, as it has a tendency to chip off, especially if it's being used on a smooth glossy base. I think the only way you could make this work and be durable would be to sand down the current coating in the spot you want, and then apply it on top. However, this is a shot in the dark, so if anyone else has an opinion, feel free to trump mine.
