I need to replace the heat shields on my Gas Grill. My grill uses individual "tents" over each of the 3 burners. The ones I am replacing were porcelain coated but are now beginning to rust out.
I can get 3 porcelain coated heat plates for $43 or 3 stainless steel plates for $19 - less than half the cost of porcelain coated.
Question 1: Will porcelain coated last twice as long as plain stainless steel? Neither choice lists the gauge of the heat shields so I can't use that to compare the two choices.
Question 2: I've seen some opinions that a rock plate is better for heat distribution than heat shields. That makes sense. However, I assume I will need a grate to hold the rock plate. A quick search showed some galvanized steel rock grates. Can I expect these to rust out just like the heat shields? Buying a rock grate and a rock plate is going to be more expensive than the heat shields, but if they work better and last longer, I wouldn't mind spending the extra money.
