Topic: Firewall Sealing with Fire Rated Expanding Foam?

I did some searching and found some previous threads saying that firewall sealing with aluminum tape and beer cans was OK.  Anyone know if fire rated expanding foam is legal?

Such as:

or

I know the frost brewed liner is good and all but I feel that tested fireproof foam would be even better in case of an actual fire. 

Thanks and see you at Thunderhill

Must be metal.  We allow very small seams and holes to be covered with metallic tape, but the bulkhead must fit tight and be made of metal.
