Done with section 22

I did the lower firewall sealing with the Firemaster sealant I received from VANs. What I received was not what I expected in term of usage. It is a dispenser that requires to mix the full content which was about 10 times what I needed. I dismantled the dispenser and did a mixing of only what I needed. Messy but doable! The question is: will the unmixed left over be still usable when I need it? Overnight the mix cured well, I was impressed that the unused mix popped out of the cup providing me a flexible molding of the cup!
