Fill panel gauge refurbishment

[CowMan]

I acquired a Bauer Unicus and the fill panel gauges are yellowed and some have lost all their glycerin/silicone or whatever is in it. Anyone successfully refill and seal up old yellowed gauges and make them look like new and if so how did you do it?

Nah. Replace the gauges. Once they crack and lose the glycerin, it’s over. They are only a hundred bucks.
