To be honest, I'm not sure I trust the info on that site. And it's because of what I found before and earlier today.
I had heard about seasoning a grill/smoker and when I looked it up, almost everyone says to do it. I'm just going to call this person the Guy, and I think he's the one that runs the site... He says to not bother. Ok.. I still want to season it, but if I get impatient, I might not.
Today when my WSM arrived, I went to put my WSM together and there's really no instructions on the actual assembly, not that it's hard. But what got me was these washers.. It came with normal metal washers and other "Fiber" washer... not sure what they're made of. I didn't know what washer went inside of the outside because the instructions were basically a picture... This got me googling and I found a Video by the guy who runs that site.
He basically says use the metal washers on the legs and "Fiber" washers on the outside for the brackets on the upper cylinder. But when I counted the washers, there were enough "Fiber" washers for every bolt.. And after looking at some other videos, I found the "Fiber" washers go on the outside and they're also used with every bolt, even on the legs... Oh, and he had the comments turned off on his assembly video, so no one can make any suggestions or just comment.
As for the seasoning... I'm pretty sure it's going to need to be done. The grates that came with it feel slippery, like there's something coating it. Maybe it's in my head, but it makes sense to me that Weber would coat them to make sure they don't rust. This did it for me and that site.
The site is specific to the WSM. You would think they would have had really good instructions for assembly, if nothing else.
