Firewall sealant
Posted: Sun Feb 19, 2012 12:08 pm
I got some 3M fire barrier sealant with the idea of using it to fill in the
voids in the firewall where it meets the 4 corner wraps. I used it between
the mating surfaces of the firewall and side/bottom/corner skins (don't ask
me why, it just seemed like a good idea at the time) when I riveted them on,
and discovered that it doesn't stick to metal very well. Now I am hesitant
to use it as the primary material in the void filling operation. It will be
exposed to fuel and oil, and aside from it's hopefully never-to-be-needed
role as a fire stopper, it has the every day role of stopping heat, fumes,
and anything else nasty from entering the cabin. I am now thinking a true
sealant material like proseal would be better as the primary fillet
material, with a coat of the Fire Barrier on the engine side.
What have others done here?
Thanks in advance. Jesse
