PJ1 makes other products aside from air filter stuff. I was referring to their chain lube. I don't see the benefits of using their filter oil on a chain, but I don't recommend it. The purpose of chain lube is to keep the o-rings in good condition so they don't crack and wear. I don't see filter spray as being capable of accomplishing this. PJ1 filter treatment is an adhesive, not a penetrant. It will simply coat your o-rings and attrack mud and dirt to them.
