I made this little handy Tool to prevent the spray of Glaco Mirror Coat Zero on the Paint of my Car. My Car is a BMW 3 Series G21. The Tool should work on any Reversing or Surround View Camera Lenses with an Diameter of 17mm.
I tested it with PETG and TPU. My Recommendation goes for TPU since it will most likely not damage anything on the Car.
Also as seen on the Picture, the Tool can be put on the Spray can for easy storage.
