Removed the cowling and nosegear and then applied the CS1900 firewall sealant. The sealant sure is thick, like the consistency of rubber. In accordance with the data sheet, I thinned it with a ketone (acetone). Took a lot of mixing. Applied the sealant with a refillable caulking tube (from West Marine). This worked relatively well. Applied the sealant to each of the rivets with an animal syringe. This worked OK, but would of worked a little better is I had thinned the sealant even more. Used a bunch of Popsicle sticks.
When it got dark, I checked the firewall by placing a droplight behind the firewall. Found 2 spots and filled them with some sealant.
