For years we've been working on a product to repair cracks, pits or
holes in exhaust manifolds, tailpipes, mufflers, or other components
subjected to high temperatures while in use. Because replacement parts are
often difficult or impossible to find, there is a real need for this type
of product in the marketplace. FIRE SEAL 2000™ is a single-component (no
mixing required) ceramic and stainless steel-filled putty that is
resistant to fuels, oils, and corrosives. After it is fully cured, it will
withstand temperatures up to 2000° F. FIRE SEAL 2000™ may be applied to
rough-surfaced or sandblasted steel, stainless steel, or cast iron.
Instructions: Use a putty knife, small trowel or spatula to apply.
Curing: Let FIRE SEAL 2000™ dry for 16-24 hours. Begin final cure by
idling engine for 10-15 minutes at a time. You may sand FIRE SEAL 2000™
after it is fully cured, using a file or medium grit sandpaper. Do not use
any lubricants for machining, but always use a dust mask to avoid inhaling
the sanding dust.
