Life of resin pigments?

I was going to order a resin pigment for a ding repair and was thinking of ordering other colors as well.

How long of a shelf life can you expect?

Thanks.

Dave

I got stuff thats still alive and well from the early 70’s. I will probably out live all of us. All that will be left on the earth will be Pigments and Roaches.
