factory coating (firewall)

[m_m70]

cleaning up my engine bay and I have this "coating" that looks like it came from the factory. Original color is underneath (you can see where I scraped some off) and looks to be in good shape. I just haven't seen anything like this on any other Broncos over the years.....

Same thing on my 70.

Most, if not all have some sort of coating like that. I have to admit though, that if I'm looking at that pic correctly, that's a LOT more than you usually find. More often it's sort of a haphazard splashing of the stuff rather than a full coating.

I believe it's just a simple sound deadening and heat barrier coating. Same as inside the doors it looks like.
Speaking of which, I wonder what the inside of your doors looks like!

thanks guys! guess I just never noticed it on other trucks.
Now seeing some seam sealer issues I'll post on another thread.

Thx much!

My 76 has some, but not that much

Some one that had it before you might have put a few sprays of flat black judging that the bolts around the sealer are painted.

I'd say it's just some factory undercoating .
