I cast with Silmar 41. I get it in 1 gallon cans very similar to what paint thinner, etc comes in. It's messy to pour and hard to dispense small amounts. I'm thinking about trying to find some hose that I can fit over the spout on the can and clamp into place, then I can close off the end of the hose, or just remove it and clean it when I am done. I'm wondering if anyone else has any other solutions.
