Acetyl cure silicones should not be used. We recommend ASi 335. It is a high quality caulking that is neutral cure, and good to 400 deg F.•Low modulus silicone means that it is stretchy, has lots of movement•Neutral-cure silicones release alcohol when they cure and have almost no smell. (Acid-cure caulking have a vinegar smell as they cure)To secure the boot to the metal, use a 16mm self-tapping hex-head screw that comes with a rubber washer.
