What Kind of Gasket and Where to Get It

My Old Country Brazos leaks smoke - and, presumably, heat - around the cc door and the firebox door. I think it's time to put some gasket material around both doors and maybe even some heat proof silicone caulking.

I searched and failed to find any post recommending what products to use or where to obtain them. Searching Amazon turned up Nomex and Rutland stove gasket cement. The Nomex (Lavalock brand name) claims to be a peel and stick product. Will this actually stick and stay in place, or do I need to bed it in the Rutland cement product? What other products are out there that I should consider? What has worked best for you?

From observation, it seems I need gasket material at least 1" wide. Does it come in black (to match the painted steel)? Should the gasket and sealant be put on the doors or on the chambers themselves? What is the best place to purchase the gasket and gasket cement (Amazon Prime saves shipping and credits The Brethren)?

What do I need to know that I haven't been smart enough to ask about?

TIA

Thank you, everyone, for the suggestions!

I got some adhesive backed Nomex via Amazon and put it on. I didn't smoke anything this weekend and don't know if this solved the problem, but I'm confident that it will. I think now that I've done something, I will forget about leaks like SmittyJonz suggested.:grin:

You've gotta love the Brethren. I got the very kind offer from wmarkw in Georgia to send me some Nomex free of charge. Thank you, Brother. I had placed my order before I saw your offer. Know that your kindness and generosity are appreciated.

best to all ...
