how do I get my smoker sealed up?

[the dude]

ok folks I have done some checking and alot of people that own a char-gril smokin pro, like I have, said they sealed the main chamber up by using weatherstriping. my question is what kind of weatherstriping are they using? and where are they getting it? thanks for helping me out folks.

Forgive me if this is a bad idea, but I found a link for setting up what the author calls a COS (Cheap Offset Smoker)
