A quarter inch of glazed creosote started a fire on Elm Street. That's basically nothing, and it still went up. I'm throwing my old gauge out tomorrow.

Actually that dampness is condensation, not your breath. The fly touching the inner tent just makes it worse.

Honestly, have you checked your shop's humidity lately? A weaker mix can let water evaporate faster off the part, leaving the actual chemicals behind to dry on the surface. That etching sounds like a chemical stain, not just a chip issue.

Totally get that. Maybe try counting the clicks out loud, it helps my sleepy brain lock in the right number.

Remember my buddy's dive in Cozumel. His computer screen went black at 80 feet. Just died. He stayed calm, pulled out his backup slate with the tables. Followed it up slow and steady. Said it was the longest ascent of his life but it worked. Never dives without that plastic card now.
