Shelf Life of acrylics ?

I have experience with Tamiya acrylics, Model Master (old formula), Poly-S/ Poly-Scale) and I have noticed a shelf life of over 2 years+. The Tamiya paints I own, some of which are more than 5 years old, and still spray and brush paint nearly like new. What are others experiences?

Well I have found some 11/2 to 2 year old Testors (the old square bottles) and the appear to be ok however most colors in the pack have sepreated pretty good

I've had some bottles of tamiya for about a year and a half by now, and they seem fine. I have some bottles of Citadel colours that I've had for 3+ years.

I dont know about acrylics but I have 6-7 year old humbrol enamels that I stir with a toothpick and spray np.

I find the shelf life of enamels exceeds that of acrylics. Once opened, acrylics should last 2-3 years at least, but enamels will last much longer.

I've got some acrylics from 3 years ago, I started stocking up LONG before I ever got back into modelling, and they are just fine.

I've also got some Tamiya acrylics over 3 years old and with a good stir they are no problem at all.
