Firewall Seam

Post by fuzzier1 »

My firewall seam has what looks like tar in the typo of it. It has cracked and is flaking out in places. Does everyone have this on their seam? It is a 1971 F100.

It's glazing compound. I replaced some when i built BC #16.
There's several different brands make sure you get one that's paintable. :thup:

I used this on my truck https://www.summitracing.com/parts/smm-39377 Level your cab before starting. Flows easily and self leveling. Fast cure time and looks really professional. Be advised! It requires a special applicator gun. I didn't realize that when I bought it. I was able to use a plain old caulking gun but took some improvising to get it to flow. One tube did the whole trough with a little left over.
