@Joeblow,
I’ve been torn about letting this link get buried and bringing it up, but I don’t want to leave it without providing some follow up.
First, I posted the wrong link. I found the product on a website with links to two lab reports, and had meant to post that one, but was in a hurry that day, so posted without checking and without comment. Then, when I realised my error, I thought I might as well follow up directly with Environment Canada as penance, so I checked their website. When I couldn’t find the report on their site, I fired off a ticket to them, attempting to obtain a link should the report be authentic and to find out if additional testing had been undertaken, because the original report was dated (A Preliminary Comparative Toxicity Assessment of Materials Used in Aquatic Construction). That was two weeks ago and to date, there’s been no response. I won’t hold my breath.
I know at one point a few years back I found the product handling info on line, but I can’t remember where and now I can’t even duplicate that search, not that it matters much. As I said earlier, I thought it would be easy enough to research, but as it turns out, it wasn’t. So, all I can find is a claim akin to “ancient Chinese secrets” and it all seems like a stinking pile of BS and I’d feel bad if anybody, anywhere, took the link as a solid recommendation.
