Hi Guyâ€™s, Newby here from Muskegon, Michigan. I need some advice if you could help. At a local auction I picked up a Heavy Duty Brinkman professional series Model #810-3214-0 charcoal grill/smoker. Cooking surface is about 19â€ x 31â€ Need help on two items, #1) There is light rust on the outside, but moderate to Medium rust on parts of the inside box as well as parts of the fuel tray. No problem getting this sandblasted but - should I paint the interior afterwards. Brinkmanâ€™s site recommends only applying oil & seasoning it - but I donâ€™t think they are taking in to account the severity of the rust? What do you suggest? #2) The food grate is missing. I can purchase a new set from Brinkman but about $100.00 in cost plus shipping. I see by many of your pictures - the use of expanded metal as a cooking grate. Now I have metal suppliers in town - but is this ok for food service? Is there a special type or specification? Any suggestions would be appreciated. Thanks, Dan.
