That's the spirit.
Not to mention an excuse to build a gigantic fire can be a fun thing as well. I still have the one that I tried to burn out sitting in my backyard. Not sure what I will do with it.
Maybe next winter, I'll take it back out to my brother-in-law's, fill it with a 40 lb bag of Lazzari Mesquite Lump and a couple old Christmas trees and light it off.
Even if it doesn't get rid of the liner, it should be fun to watch!!
If you can get it down to bare metal, you're good to go. I think that a certain amount of satisfaction comes from cooking on something you've built yourself. It will be well worth the effort, my friend. They make some awesome Q!!
