Hi Jim.
I'll bet you're thinking of SilverCreek. He used to participate regularly in this forum and shared some very thorough and well thought out information and he also produced uv resin on the side. You can find mention of it in several blogs and forums -- eg, https://www.garyborger.com/2019/02/0...d-head-cement/ -- if you google "silvercreek uv resin". I have no idea if he's still in the uv resin business.
