I've been learning a ton from this forum, thanks for the all the help. I got my Egg used and the cooking grate is somewhat rusted. I am temporarily using a Weber 17.5" grate, but looking to replace that (and be ready for the extender). I thought I could either buy the BGE stainless or cast or alternately just buy Grillgrates and put them on the current grate. Looking at the old grate it is definitely not stainless so it may have been porcelain coated at one point so I don't think I can restore it so using it to just hold the grillgrate might be worthwhile?
