I’ve been using PU18for a couple of years now, both inside and out, refurbing silicone which has shrunk and cracked. It is a bit stiff to use in cold weather, (warm it up indoors before going outside). Paintable and seen no deterioration so far
Helsian pliersAKA Virgin urgers. Used to expand hessian sleeve in conjunction with a lubricant, before heat shrink. Still have a pair. Use to fit heat shrink tube on cables
