West System Epoxies

How old was the 207 hardener? It can age rather quickly in the can.

I kept a couple of medicine cups with the mixture in the bottom dried from left over and put them on the window sill to see what happened. Six months later they looked like pee. Sure this is an extreme UV test but inquiring minds want to know.

And yes it ages quickly in the can, don't buy much quantity.

I saw no advantage over 206 which I did the same UV test on.

Can you leave the pumps in the cans all the time or do you need to remove them if you aren’t going to use them for a few days?

I'm not sure if this is agains the rules or not, but if you are using a lot of epoxy, this system is well worth the price.

Leave them, the mess created by removing/cleaning them each time is not worth it.
