NAro,
I'd already thought about rubberizing some of my knife handles...  but I hadn't even considered coating my kydex holsters with the stuff.  Sweeeeeeet!!  <img src="images/graemlins/smile.gif" alt="" />
Given our shared interests, do you post a lot over on packing.org?  If so, I probably owe you another thank you for steering me to this site.  Somebody over there told me about this forum, but I can remember who!
Thanks, man!
