In my never ending quest to make "everything" right, I didn't like the fact that my firewall insulation was pulling away from the firewall over time, which was much more visible while I had the strut bar removed
But I also recalled that when things were warm under the hood, say after driving, I noticed that the insulation was much more flexible, which got me thinking
If I could heat it up, I could probably bond it back in place, thinking contact cement would do the trick
So I grabbed one of the missus' hair driers (she is a hair stylist, after all ) and gave the insulation a good blast, and sure enough, I could form it back into it's original position
And no, not the $400 Dyson
I used Wellwood contact cement, this stuff is awesome, if used properly, which requires applying to both surfaces and letting it become tacky to the touch, after 15 - 20 minutes or so, but can be used up to 2 hours before you have to reapply
Then I heated up the insulation and slowly pressed it back into place, using work gloves, as it got rather hot to the touch
Here's before and after shots, I do like the results and one less thing bugging me under the hood
Firewall insulation pulling away? No problem!

Very nice Bobbo.
My car has got the exact same thing, will get the hairdryer to solve it

Re: Firewall insulation pulling away? No problem!
Hey Paul, you can also use a heat gun of you have one
I have one but when I turn it upside down, it sounds like a blender full of marbles
Be careful and work slowly, as you can see that some of my insulation broke off due to being brittle
I bet a lot of our 6ers have this issue and most of us choose to ignore it

How does the Wellwood contact cement handle the heat of the engine bay?

Re: Firewall insulation pulling away? No problem!
Hey Tim, good question
I'll have to check the can for recommendations regarding high heat, but I think it's fine
The supplier of the hood pad I have (classic 9 leather shop) recommended spray contact cement, so I would suspect that heat isn't a concern
Plus some of that did come loose and I used the Wellwood to reattach those portions, and it ain't going anywhere now
Edit: The container just states for use in high temperature environments, and that it should cure for 72 hours before subjecting to heat over 150F
Oh, and it's actually called "Weldwood", not sure where Wellwood came from

Re: Firewall insulation pulling away? No problem!
Ok excellent, thanks!
I am also trying to find a product to re-glue my rear speaker pod vinyl back onto the metal carrier.
Those suckers get really hot when basking in the Aussie sun!

Re: Firewall insulation pulling away? No problem!
Interesting, I have to get back there as well, not for the speaker pods but for the cover I made for the parcel shelf
It's vinyl as well, and I used spray contact cement (a 3M product, IIRC) but it doesn't hold as well as the Weldwood stuff
But I would recommend this product for rebonding the speaker pods, apply, let set for a few, and clamp in place
Here's a couple of pix, one of which is the rear parcel shelf that I need to reglue

Brilliant, thanks. I'll start searching for it or something similar.GRNSHRK wrote: ↑Mon Feb 06, 2023 6:59 pm Interesting, I have to get back there as well, not for the speaker pods but for the cover I made for the parcel shelf
