No, I was looking at their Green Polyurethane stuff.

It may be ok, I guess the only way to tell is try it and let us know.

Are you looking at the same product that I am? This says that it "...fills gaps and irregularities". Isn't that what is meant by being able to expand to fill gaps or does that mean something else?
Until someone tries it we won't know. But as the ad copy wording doesn't specifically say that it expands when it cures, my assumption is that it doesn't.

Well, I think I'm going to try it out on something simple to see how it works. Any suggestions as to a good experiment to see if it expands like PL? Could one just use some of each to fill some holes in a scrap of wood, let them dry and observe the expansion? Or would it be necessary to join a couple of pieces and examine the joints after they dry? Probably want to do the latter anyway to subjectively test the joint strength.

Put a bead on a piece of cardboard, if it expands it will be very obvious, the regular stuff is about 2:1.

Thanks, Bill. Simple enough. OK, I just ordered some and I'll report back once I try it out. The only place that I've found to get it from so far (I guess because it's a relatively new product line) is www.buygreen.com. If it doesn't expand the way PL does, I'll admit defeat, use the rest for some other projects, get some PL, and just start building some cabs. 8)
