Old Country Wrangler Smoker

[smoking works]

Okay guys, just custom ordered a charcoal basket for my Wrangler. L: 14" x  W: 12" x H: 7.5" (hopefully I measured correctly and it fit).

Now I need to seal the gaps on the door edges.

Can anyone give me some advise on a good high temp sealant that will work for this operation?

Anyone?
