My DH works with a gal who does triathlons, and she told him that the LBS put this Stan's sealant into her tubes on her Litespeed, and that it has worked great for goatheads and the like. Kind of like Slime, but different, I guess. She didn't have much other info, since the LBS did it for her and she is not the type to ask a lot of questions, so I was wondering if anyone here had any experience with this stuff.
