Just picked a drum from a bakery that had canola oil in it so should not have too add anything to it when i season it should i? the inside of the drum is stainless so that makes it a kittle easier. On the outside of the barrel it is painted black, do i need to grind off the paint and spray it with high temp paint? Do i need a water pan? There is no holes in the lid so what type of exhaust hole would you reccomend? One more, if you do not have an access door how do you add wood chunks/ chips or do you not add any? Thanks for any help,I have never smoked anything before. Between charcoal briquettes or lump is one better than the other in the UDS? Thanks again
