The Hobie cleaner and protectant is two products by McNett.
The UV protectant is formulated to soak into plastics and vinyl to actually rejuvenate the materials. This is not like Armour all which is more of a coating that simply wipes or washes off.

UV Tech is a powerful protectant for use on hundreds of items including dry suit seals, kayaks, binocular housings, boat covers and a variety of outdoor fabrics and materials. Rejuvenates synthetic and natural materials and protects surfaces from sun damage and color fading. Restores gear to its original condition and prolongs gear life.
