Yes, plastic will work fine as long as it has a decent lid. I had a container with a mediocre lid and leftover VC17 almost lasted a yearDo you know if the paint will react with the plastic over a winter?
I buy small metal paint cans from a local company, and use those for any leftovers so that i can have multiple 100% full containers, thereby preventing evaporation.
I wonder if I can use the plastic bottle as a storage container instead of the metal cans ?
I think a call to interlux is in order.
