SW Motech guards come with black nylon nylon protectors that wrap around the frame under the clamps. I dont know if any of the other brands include them. Quite a while back I bought a 6" wide X 12' long roll of Trimbright "Bodyguard" clear self adhesive ( has peel off no stick backing ) Mylar at the auto parts store, thinking of doing a chip guard strip on the rocker panels on my car. Decided against it, but have used the stuff for all sorts of protective applications ever since. It is thick and durable enough to use to line the engine guard clamps, or wrap around the frame for under the clamps, plus it is clear. Similar to the clear tank protective film others have mentioned, but probably thicker. Have a windshield with mounts that clamp to fork tubes, or handle bars? A wrap of this stuff around the handle bar or fork tube first, will prevent marring, so if whatever is clamped on is later removed there will be no marks left behind. It is a cut to application size product, and easy to work with. My roll has lasted a long time through many applications, and just happened to be what I had on hand. I imagine the this stuff or something similar is available in a smaller quantity with a little research.
