Suitable for all weather conditions our unique water repellent, ceramic, non-fling formula penetrates deep into the chain link, creating a durable protective coating that guards your chain against corrosion and metal to metal wear. An added benefit to our unique formula is that it includes a UV dye, which means you can use a UV torch to make sure youve hit every link of your chain. Be sure to wipe away any overspray. Go longer between applications, with greater protection for your chain than ever before!
