Have enjoyed this grill for less than 2 years and I love it's performance BUT the cast iron grates just don't hold up. I have many cast iron skillets that I use primarily for the reason that cast iron allows flavoring to certain foods, like meats and veggies. I know how to season cast iron for this reason, it gives sort of a stick free pan if you do it right. I have done this several times for my grill but they are rusted so bad that Even though I keep them clean, bits of metal are showing up in the food cooked on this grill(Barron 550 NG). I'm concerned that someone is going to ingest a big piece of cast iron and I don't know if that is good. I'm goung to see if I can find new cast iron grates that don't peel off like these do.
