6800 power button

[redfish]

Today I dropped my xv6800 on a tile floor. For some reason it broke the (rubber) power button. I was a verizon CO tech for 30 years so instead of $50.00 for insurance, I opened it up and found that the switch was ok but the rubber (latex) button was damaged. I had to remove it.
Does anyone know where I might find a replacement button. I am sure salt water from our lovely Chesapeake bay will find the opening.

Thanks
Jerry
