I agree with John
I agree with John. Old school. McDonalds used a mix of more than 90% beef tallow for thier friers. Its cery versatile stuff. From cooking to airplane fuel. Flux for soldering to leather conditioning... soaps and it was even used a gun lube in the Civil War. I used it for restoring leather jackets and baseball gloves. Never on a fly line. Im still new to fly fishing. Im probably going to swing by a sports shop and grab a tube of tallow based conditioner. It works on synthetic gloves and is safe for plastics as most gloves has a polymer logo sewn to it.
