i am looking at buying a used pellet grill, the exterior is mint, the pellet pooper and burner are fine and work well. the interior is rusty below the grates. the grates are also in good shape. can i just wire wheel the rust off the flavor guard as its called and use a high temp bbq paint on it ? where i live there are less than a dozen pellet grills in the whole town and NO BODY has ever seen an RF smoker/grill except on tv ... ha ha ha. i would just like to add one to my arsenal of smokers and grills and get away from the old broil king propane grill i have.... the pellet grill can fire up about as fast as a propane to burn up a steak or 2... THANKS FOR ANY INPUT.
