High temp rubberized coating

[DarthChicken]

I'm looking for some ideas here, and thinking this is one that could benefit all.

I'm tired of the rattle of fiberglass. I want to coat the underside of all of the fiberglass with something that will cut the rattle, not peel or melt with engine heat, and adds minimal weight.

I'm really unsure of what to use though. Bed liner? Tool dip? A silicon based paint?

Ive used the tool dip rubber stuff in one area but it just rubbed off with the vibration.

McMaster has high temp silicone in a variety of shapes including adhesive backed sheets. I see max temps on the cushioning foam silicone to 400F on the silicone and 300F on the adhesive. 1/16" to 1" think up to 3 feet sheets. That should work for most areas.

Because of the irregular surface that exists on the rough side of the fiberglass, I'd rather use a brush on solution. I'm thinking every piece, even the seat.

The adhesive backed fiberglass heat barrier that I stuck on the underside of the tea tray hasnt pealed up after installing it several years now. I cant think of something that you could spray on that would be heat resistant and not add a ton of weight.

Wonder what dealerships use for undercoating when they try to sell a winterized package to you. I bet that stuff would be perfect.

Might wat to try a single can first before ordering enough for the entire car

Good call Silver, I was thinking of that stuff when he posted and was going to look it up.
