The only thing mine states as a fact is that I should reduce the tension when
it is raining and to take it off when backing. Sawdust. Question: The
rounded trim around the bottom of my l973 Airstream was badly dented, to I
took it off and use rubber hammer to take the dents out. That worked, but the
aluminum now shows stress marks, plus it does not polish worth a darn. Any
suggestions? Sawdust.
