Hello all......my cousin is tight on funds so asked me how she could save some ole rusted Q300 grates. I had here scrape....and wire wheel clean. Then I had here use cooking oil at high heat applying every 5 to 10 min until a black candy coating had been obtained. Everything went as planned but the areas of real bad rust didnt take the seasoning......does this mean they are just too far gone or does she have to cook some bacon on that rust
