Having previously lived in desert southwest never had to worry much about moisture/rust on a grill. I've had this cover for about 4 years now (living in the southeast). The material has held up well, however the seams have not. Every place it has been sewn together the stiches have ripped. I will have to find a good canvas (or something similar) sheet to cover the grill so I don't have to worry about the seams. Would I buy another one? Undecided.
