Livorsi bezel popping off
 

My livorsi Mega trim gauge is having an issue with the bezel popping off when I tighten it down. I've only finger tightened it but it still pops off. I called Livorsi but they want a copy of my invoice which I don't have because its a used guage. Is there a way to crimp down the ring myself so I don't have to send this in?

Glue it back on with "seal all" adhesive. When I purchased some colored rims from Livorsi, thats what the tech guy told me to put them on with.

Where do you by seal all at?

Any hardware store, it's common stuff.
