Can she provide MSDS sheet for the stuff (needs to have one available, by U.S. regulations)?
My only "contact" with the Sandalady was a few years ago, and I asked about repairing my old TG-12 (I didn't know about this board, or Kenny Jenkins at that time). She quoted about $150, but said it would take over six months, so I thanked her and did nothing. I just thought that was an awfully long time to take to repair it.
2008, Kenny Jenkins did its full fix for me, in under a week.
