One shot back into the can?

One shot back into the can?
When I finish a job I usually pour my paint back into the can but I remember someone advising against it. Any views?

Re: One shot back into the can?
I never return paint to the can. I used to do it years ago, and noticed I would often get "seeds" in the paint. Seeds, being little grainy bits of semi-dried paint. I don't get seeds these days.
The conventional wisdom is that is makes the paint go off much quicker. Short of a controlled comparative test, I can't say definitively that this occurs, but there is good logic behind the assertion.
The paint, while it is in use, takes on a lot of oxygen due to constant working and dipping of the brush into it. Especially if you've been writing for a while, and have added a little turps to keep the viscosity correct. It may still seem nicely liquid and unchanged, but it has already started to polymerize. If it is added back, the theory is, it speeds up the process of polymerizing the whole tin.
