I like the fact that they're testing it with pressure treated lumber. I hate using green treat lumber. I know it's supposed to be less hazardous than it was in the past, but I still don't think it's good for the environment. And I certainly don't want my granddaughter or another little kid touching something I've build from green treat lumber.
I haven't used the SoyGuard products yet, but it looks like it's worth a try. If you've used SoyGuard (or a similar product), share your experiences in the comments section below.
