I have had my Chargriller Kamado for about 7 months now, got it at Gander Mountain and really love it. It is outside under an overhang and is covered when not in use. So far no signs of any rust or paint blister. Chargriller customer support is very elusive on this product, about all they were saying is that it was an exclusive for Menards and had no comment when I asked about the Lowes rumor that obviously was try. Overall a great unit for the price and all I did was put some thin cork gasket material under the frame of the lower air intake to make a better seal where it was screwed onto the side. Took care of the only air leak I could find.
Thanks JM for reinforcing what I have been saying about the Big Red Kamado, even though mine came in black!!!
