Those Sharp Edges
If your like me while cleaning or doing maintenance and cut yourself on the battery box lid or the rear bumper latch and cover. Head over to your favorite Automotive Parts Store or search on Amazon for a roll of thin self adhesive black door edge guard trim.
I installed it on the rear bumper lid, battery lid the exterior stove exhaust vent and the entrance door aluminum rain drip rail. The trim goes on easy and removes just as easy. Gives the black areas a smooth very nice finished look. On the aluminum or stainless it adds a sharp contrast. I got this idea while visiting the Airstream factory tour before Covid. While in assembly they cover the sharp areas with this material then remove it.
