Answers:    If you leave it out in the rainfall without a cover, it will rust. They are pretty cheap compared to replacing a grill.
Did You Know?
We use one all the time. Keeps it looking bright longer and protects the finish. Also we put armor all on rag and cleaned the ole grill, looks resembling a new one. Did a great job.
