yeah erle
i was thinking of getting triumph pads and then inlaying the diamond plate in there somehow. The main problem i was having was that theres a slight compound curve on the tank. Theres the main inverted curve headlight to taillight, and then an outer curve bowing gas cap to engine.

But now that you mention rubber edging, i wonder if that fender edging for cars, that guys use to line the underside of the tank would work?
