We reached out to Dischem (Andy Thompson) and he is providing many of us Ebeamers in the US with our HSQ. He is actually in your backyard in western Pa. He packages up HSQ into the same/similar thicknesses and solids content that Dow did. He also will make small quantities and ships fast. I just bought a 20mL bottle from him which works great for us. Happy to share more if you are interested. It’s not cheap, but it’s inline with the trajectory of the HSQ from Dow before it skyrocketed.
