We are comparing K2 liquid silicone sealant for glass and lamp gaps, universal, 21g with several alternative K2 brand products, including K2 Alpinist Ski Brakes 90mm for Touring Bindings, K2 Wayback / Talkback 84 ECOre Skin Climbing Skins Mohair Mix Blend 167-174 cm, K2 WAYBACK / TALKBACK 88 ECOre SKIN mohair mix blend 181, K2 WAYBACK JR Skis 136, and K2 Alpinist 12 Ski Touring Bindings without Brake.
