Firewall sealant and Fire Safety
Can anyone recommend a source for a firewall sealant that can easily be mixed/dispensed in small quantities? Each time I need a dab, I can use Pro Seal but the shelf life is short and I can't find a small quantity at a reasonable price. What else might be out there? The high temp RTV is only rated to 600 degrees F.
Thanks in advance! Jim

I have used expired proseal on various things. I wouldn't use it in a fuel tank but I used it on my firewall.

Keep your ProSeal in the fridge .... you do have a beer fridge in the shop, don't you? It will last for years. No worries using it for jobs like this.

Firewall sealant...
Pro Seal (for fuel tanks) is NOT a good firewall sealant! I don't know what temp it's good for, but it's nowhere near 600F, and it burns.
Vans sells a firewall sealant, but it's not cheap and has to be mixed as well (maybe that's the stuff you are talking about). I used it to seal my firewall and all the openings I could at that time. The rest got the Hi-Temp RTV.

My plans from vans said use (fuel tank sealant) on skins to seal to firewall flange.

The 3M product that Dan cited is what I bought at Home Depot - expensive tube, but if it lives up to its claims, it should be well worth it! I used it for the firewall recess on the -3, and will be using it for the rest of the -3 firewall sealing job as well. Much better high temp properties than Red RTV, FAR better than pro-seal.
