UV Protectant maintains the integrity, suppleness, and elasticity of the latex, rubber and neoprene in drysuits. UV Tech contains a powerful UV-blocking agent that protects the drysuit neck and wrist seals and a re-plasticizer that dramatically slows degradation of drysuit seals. UV Protectant does not contain silicone, penetrates instantly, won't rinse off, and surfaces treated with UV Protectant will not attract dirt. Depending on sun exposure, even a single coat of UV Protectant can benefit your drysuit for an entire season. If an item is getting heavy UV exposure, we recommend using UV Protectant once every 30 days for maximum protection. We also recommend applying UV Protectant before long-term storage.
