Give a call to WT Tool in Stoughton, MA. Ask for John Kattinger (manager) . . . John is current or former Pistol Team Chairman for Sharon F&G. Tell him what you need and how much of it and I'm sure that he'll take good care of you. He's a real nice guy.
I suspect that they carry this stuff or another brand of the same thing.
