Ptex Red seals everythingIt is a CharGriller. Model 6125. I saw it at HD last year and it jumped out and grabbed me. It was $299 instead of the $199 you're probably used to seeing. Other than using Permatex Red while assembling, there are no "mods" other than some steel plates for baffling and a charcoal basket. Everything fit well and the doors are aligned and snug. I think it compares with the OK Joe in quality if not size. I love it.
