it's stainless steel, worst case sand it down and then re-polish it. I have a stainless steel kitchen sink out back next to my grill, once or twice a year i just take some high grit sand paper to it and then use bar keepers friend (BKF) to make it last. To get it to shine, just use some polish. I got my #2 on new years of last year. It's been great, granted i have 2 other smokers that i enjoy to use more in the summer, but the season for the smokin-it is arriving soon!
