Hi, I just finished assembling my new CG Duo with SFB last night. Today I plan on seasoning it. I shortening to coat it with and spray canola oil for any hard to get to spots as well as lightly coating the outside of it. My question is when I season it can I do it all at once; gas side, charcoal side, an firebox? Also, on the coal side is it better to season each part independently. Meaning should I coat the main section in shortening and put the coals in there and then coat the SFB and then put the coals in there? Or should I coat both the main body and the SFB and then just put coals in the SFB and not the main grill section? Is there anything else I can do preventive maintenance wise in order to get the longest life out of the unit? If I am seasoning it and getting that protective coating built up is it a good idea to also line it in heavy duty foil? Should the SFB be lined in foil? Thanks a lot in advance.
