My WSM is 11 years-old and my Performer is 10. They are all original - grill grates, charcoal grates, WSM door, etc. I'm thinking of giving them a facelift; new grates, new door, a GOOD cleaning, etc. My son is a welder and has offered to replace the rusted parts on the Performer frame. It won't change the way they cook, but I feel I owe it to them for all the pleasure they've given me over the years. I'm leaving the 15 year-old Silver C gasser alone; only my wife cooks on it.
