I have been deliberating quite a bit this last while on how to use fire barrier with the firewall. Talking things out with a friend we reasoned that it was a good idea to place a small film of fire sealant between the aluminum angles and the stainless steel firewall. The thinking is that if the aluminum rivets melt away in an emergency, there is some protection there for the fire barrier to do its job and close the rivet holes off. As well we were discussing the fire barrier would act as a good means of protecting the aluminum from corrosion as we didn't feel it wise to prime that mating surface.
Also in the research, getting CS1900 firewall sealant to Canada is not easy. Frankly it is darn near impossible. After lots of research, I ended up accepting the fact the only project I can get in Canada is 3M Fire Barrier 2000+ through aircraft spruce. Its the only "high end" fire sealant they sell.
So tonight, I spent some time getting things all set up and ready to go as I will need to finish riveting as fast as I can as I will be working on things "wet"
