Reusable? No. I wouldn't re-use any jar for DN. I had my wife buy a dozen Ball canning jars at the local Dollar store. If it had been too expensive, I would have heard about it! If you dip lures, your DN will eventually begin to cure. Whatever you do - Bloxygen, etc, etc will delay but will not prevent it. By decanting into canning jars and using Bloxygen, I've kept DN for about a year, max. I've come to accept it as the nature of the beast because I REALLY LIKE the ease of use and the final product you get with DN. You can use epoxy on wood crankbaits and it works fine but there's really no substitute for DN if you want to coat metal spoons or dip repainted plastic baits.
