HOWDY TO ALL,
I can't remember where we purchased our fireproof sealant. I have some areas that need attention on the firewall.
There is a 3m Fire sealant at Home Depot also, the 2000 series.
Can 3M FIRE BARRIER 2000+ be substituted everywhere one would use Red RTV?
Depends on where you were using red RTV.
I use 3M FB2000 on firewall edges and penetrations, Permatrex Ultra Black (aka Loctite 598) almost everywhere else. Not as corrosive, highly oil-resistant, and lots better looking in an engine compartment.
You have to be careful choosing a fire barrier caulk. On my Lancair I used the stuff that came with my Firewall 2000 Ceramic Blanket kit - 3M, I think. Over the years, it ate into my engine mounts.
I'm afraid not. I threw the tube out over twenty years ago. Here's what it did to my engine mount, though:John, can you identify the sealant?
Hi Dan,Hmmm. I suspect latex sealant, or one of the acid cure silicones, but I'll have my cowl off today for a condition inspection in progress. I'll take a hard look at the FireBarrier 2000, now going on 9 years since installation, in a humid deep south climate.
