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

I used the CS1900 firewall sealant from the Van's online catalog. Here's a
link:
http://www.vansaircraft.com/cgi-bin/cat ... ion=search
There was more than enough to seal the firewall corners, inside and out.
This is a two part sealant contained within the application tube. You mix
the two parts in the tube, and apply it from the tube. It looks, feels,
mixes, and is applied just like ProSeal.
The only issue I had was the application from the tube. It was difficult to
get the tube into the corner areas of the firewall to get a good fillet. I
ended up cutting open the tube, scooping the sealant out and applying it
with a popsicle stick. Once it is mixed you have to use it. It should be
much easier to apply if the instrument panel, rudder pedals, etc. have not
been installed, or if it could be applied during assembly of the firewall
to the fuselage.
Hope this helps,

Norm,
I used the CS 1900 sealant from Van's Aircraft. I believe it is rated to
2000 deg Farenheit for 15 minutes. It is very much like Pro Seal, which I'm
told has also been used to seal firewalls in experimental aircraft. Here's
the URL:
