You know those heat-shrink thingies that you put on cables and lines and such? They shrink up when you heat them up with a flame? My friend and I need to put bungies on our NDK hatch covers (b/c NDK doesn't do it and neither did the dealer and now we are at constant risk of losing the damn things!). My friend got the light-weight bungie material but doesn't know where to get the shrinky things. Figured you guys would know what they are called and/or where to get them!
