Firewall sealant

When Ford assembled the cars they but a black sealant on bolts and nuts etc. that came through the firewall. What is the best material to use When replacing items on the firewall.

Also anyone have suggestions to get the firewall pad plugs back in a 68. Seems like I would need to drill out the holes larger to get the repro plugs to work.

For the rubber plugs, here's what I did. The rubber plugs are thin walled. If you use much force pushing them in, the end will punch out. After I ruined a few of them, I took some small thread from a piece of paracord (internal part of the paracord) and tied it to the nipple end of the plug and pulled it thru the firewall with no more breakage. Others have had success using screws threaded in them and pushing. Also using different objects to push them in. I tried without success until I used the strong paracord string to pull them thru.

Thanks, great idea withe the cord. I third threaded screw since the plugs seem threaded but that didn't work and like you I ruined a bunch trying to push or pull them through with various tools
