The journey began by scratching up the phone.  Without roughening, the hot snot didn't stick.

Hot snot was applied to the rough positions.

Hot snot worked quite well as phone armor. It's the most pristine phone lions have ever had after 8 months. It ejected from the truck a few times but seems to have been protected.

The best protection for the camera has been a vertical hot snot line. The horizontal lines wore off.

It all melted during the heat waves & had to be replaced. There are still dreams of incorporating these bumper positions into a TPU thing which doesn't require scratching the phone.  The TPU sock would be double sided taped to the phone.

There's still a lot of adhesive goo accumulation from the holster's tape but making something which completely eliminates the holster would take a lot more space.
