Hi All;

While I'm trying to figure out my electrical problem, every time I remove this piece to access the fuses/relays I get more and more crumbled pieces from the degrading underlining all over the place.

Can anyone recommend a decent product I can brush on to stabilize/seal this material that preferably would be available at the local hardware store.

Thanks!

You can try some Loctite spray adhesive at Lowes. Spray on not to attach to anything, but to act as a layering/binding agent.

Add: use the Loctite product - no the 3M spray - they are not the same and I think wouldn't be good for your goal. The Loctite is less viscous and does not cure so fast - will give time to layer it thinly with your index finger. The 3M stuff is thicker and cures as soon as it hits the air.

That would be a nice piece to remake for Jerry Feather. And it's not that complex; shouldn't take years to develop.

FLYVMO

If you do not wish to remove the stock insulation piece, one product to seal the foam and prevent it from crumbling is a plastic-dip spray. It creates a flexible coating that allows the foam to "move" slightly but it will prevent pieces from crumbling away.

The preferred way I would go is to replace that crumbling foam with some modern closed cell foam. It is amazing how much of that old car smell you get rid of when replacing those old foams.

Here's what I ended up doing.

For what its worth, I'm posting it.

Took all of 15 min- and produced an acceptable result. However, maybe somebody here can suggest a better product to spray on- (perhaps the one FLYVMO mentioned............

great fix!

I was considering recommending the spray on rubber but I had used it once on something and it was problematic. The delivery agent was very 'solvent like' and altered the surface it was sprayed on. I was afraid the foam wouldn't stand up to it well. I thought the Loctite worked well and was pliable too.
