Hmmm..
Q926 is still in a pending state, but the new R77g makes the answer obvious.
Add 3946 to the "side rails" club. We have tried to keep things tight enough to repel 10" boulders from our innards, but we may have to tighten up some more to repel 8" vinyl strips. Fortunately, we have some similar strips under the chassis workbench so we can do some testing this week.
