What to do with extra paint?

[Milo]

What should I do with extra mixed/thinned paint when I'm done with a certain model or with that section of airbrushing?

Personally, I keep some mixed paints on my workbench in containers I kinda fudged together.  I found lids from some of the older Evian water bottles would snap tightly onto the lid from a 20 oz soda bottle and keeps a tight seal.  I saved a bunch of the lids and just reuse them once I no longer need the color or it degrades.  But I keep some custom things for long periods of time this way, like a rust paint I use on exhaust systems.  Paints will keep for a long time as long as the container seals tightly.

I use these:

They seal tightly, with a gasket in the cap. The paint for my dragster has been in them for a couple of months, now and I've yet to thin them, again. I've had some other mixtures in them for a couple of years, or so, and they're fine, too.

Tamiya has 3 different size jars you can buy. I own a ton of the 45mL jars, but there bout $3 a jar.

I decant cans and needed to store the extra paint. I got a set of eye dropper bottles with labels from Amazon.

The set I got are no longer available but I am sure you could find something similar.

Whatever you do don't put the thinned paint back with the unthinned paint. You run the risk of all of the jar going bad as the thinned paint composition has been changed.
