I bought the "clear" 3M tape yesterday from the local hardware store ($1.50/ft and I bought 3 ft). It was super gritty, I was afraid it would tear my boots and pants up but that wasn't the case. I wear Tech 8's and all it did was smooth the leather calf part down on them, no noticeable wear on my pants either. But, most of it wore off after 3 hours at the track today. It helped a lot, mainly kept me "on" the bike, rather than slipping towards the rear under hard acceleration. But, like I said, most of it wore off. The stuff that TP uses looks more like a thick rubber or plastic sheet with BB sized nipples on it. They look like they would "flex" a little more, you know, give a little without tearing your gear up. Anyone seen or tried this stuff?
