I have a bottle of Alclad copper that has gone bad. It was previously opened and a small about used and the paint had now turned into a jello like substance with the copper pigment settled at the bottom of the bottle. It was well sealed. I've never had a problem with any Alclad product other than a black primer years ago that never would dry. Has this happened to anyoine else?
No, i have had a bottle of Aluminium thats been opened several years and had no issues. I can only think your bottle got contaiminated some how.

Two ways to turn paint to jello: contamination or air. Thinned paint returned to the bottle with some brands or with certain thinners will do this, not sure Alclad would qualify. Or the lid just wasn't sealed as well as you thought it was.
Try putting an agitator into the bottle, and shake it vigorously. You can use a couple of BB's, or a nut, or a bolt. This will make it work like a rattle-can, and if the problem is just separation, it should restore the original mixture.
I put a hex nut into each bottle of Alclad when I first opened them, and shake the hell out of it before each use. Works for me!
Gimme a pigfoot, and a bottle of beer...
I use a Badger paint mixer before every use with every paint I have, including Alclad. One word of warning though on using a mixer or any metal object in the bottle is that there is always a possibility of breaking the glass. I have actually done that once, when I was using the mixer on the bottom of the bottle. A whole bottle of Alclad isn't fun to clean up. Try using a bamboo skewer first to see if you can get the gelled pigment moving again and get it broken loose from the bottom. Some of my older Alclad bottles, when I need it to spray in a fine stream, I'll add a little Gunze Leveling Thinner to it...but only in my mixing cup. I don't put any thinners in the bottle because of the possible contamination reactions that OMG mentioned.

Thanks for the ideas. I'm assuming I didn't have the bottle as well sealed as I thought. To be safe I'm tossing it out. It's so thick it doesn't flow even when upside down but giggles like jello. I've never seen that before.
The hobby shop I go to has a rack of Alclad bottles that are rather old (they stopped carrying the brand years ago) and many of them are well short of being full so apparently even when unopened it looks like they can evaporate over time. None of them have turned into a jel like the one I'm referring to.
FWIW, my oldest bottles of Alcad would be going on 8 yrs now, are all still fine.
