I don't know that I'd go to the effort of even using lard. I know it's cheap but it's messy too. All you need is a very light coating of spray-on cooking oil. You can either buy a can of something like PAM or similar. I used my olive oil atomizer to coat the inside of my drum and wsm with a very light coating of EVOO. I probably used less than 1/4 cup to do the seasoning on both smokers combined.
