has anybody ever tried anything like this?

does it work? or does it just melt on the pipes and make a stanky mess?


in the past, i have been advised to stay away from header wraps. the logic was that exterior condensation would collect in the wrap and promote rusting.

would this be the same ?

D~~~!

I've seen some spray (like this) you could soak header wrap in to seal it so it can't hold any moisture against the headers. Any wrap made of fabric has the potential to hold moisture. The one you showed looks metallic - if it's just a foil like barrier I don't think there will be any moisture problems, but if its foil backed fabric then we come back to the same story.

They also sell a DIY spray on ceramic coating now, that's what I opted for.
I think it's the same stuff Doc coats his pistons with...

I've used the DEI hi temp coating on my wrap extensively. It works very well.
It's really a one time use item, so don't plan to store the can after you've used it. During application the nozzle will plug, so you need to keep turning the nozzle in the top of the can to keep it flowing.

There are various products for header wrap coatings. Volcanic ash, and so forth. If you look carefully at the heat ratings and how they insulate, you will likely find something that suites your application. Some of them are mighty pretty too!

I haven't used a blanket for the duals on the head pipes, but do use a similar blanket over my starter in conjunction with wrap on the head pipes and the DEI coating. So far, no problems or complaints. My under-hood temperatures are substantially lower, and my tailpipe exhaust temperatures are much, much higher. Don't put your hand over the tailpipe after I've made a pass!

can i assume that spray coating is intended to be applyed when the headers r off the engine and can be flipped over to get the back side? seems to me that getting complete coverage while mounted could be next to impossible.

Yes. Off the engine is much easier.

The wrap is applied wetted with water to make it pliable. It must be completely dry before the coating is sprayed on.

I had to do some touch up under the car, and it was a real pain.
