I agree with this. I'm super paranoid with fire rope because of the fiberglass, silicone because of fumes and who knows what, galvanized coated stuff, zinc coated stuff, etc.... So I used a food grade silicone to seal up my UDS lid. I rarely go above 300+ so any of the food rated silicone should be more than sufficient.
(then click "Silicone Adhesives/Sealants" and you will find them on that page)
RTV 103 is black and good for up to 400 degrees.
RTV 106 is red and good for up to 500 degrees.
I avoided automotive grade because I've heard something about formaldehyde at certain temps. But even then the RTV103 and 106 you get more for about the same price as the automotive grade stuff and shipping for me was pretty cheap. I think I had it 1-2 days after I phoned in the order.
