Need advice on replacement of failing Cameras.

I'm a bad example. But I skipped the fake rubber plate gasket, and siliconed the back, the front, and used no dielectric grease
It's a test so @sebastiantombs can yell at me next year when it fails and say " I told ya so-moron" :)

Looks good, I picked up some items from your list today. sill be sealing mine better when I get some new ones.
