My local HD doesn't carry the silicon sealer that Migraine recommended, so I tried this one instead (
http://www.homedepot.ca/product/silicone-seal-tape-1-2inch-x-1-4inch-x20feet-black/864990). I've smoked twice since installing it. The first smoke actually melted the gasket, and gave the food a very overpowering (and disgusting) rubber smell and taste. Before my second smoke, I tried to remove what was left of the gasket from the doors, but the smell and taste were still there (although not as bad, but still very strong).
Would something like this stove gasket (
