We have a Webber Q 3200 as our outside grill for about four years now. It was an excellent grill in the beginning. Started easily and got to the right temp quickly. After about a year the porcelain on the iron grate cooking surfaces started to crack. I followed some Ruth Chris cooking methods of searing steaks at 500 degrees and I guess it was too much for the surface to handle. Now the surfaces are rusted out. Everything else is running fine. But the surfaces are unusable now. We have to cook at low temps and on foil.
