Hot paint

Would it make sence to wrap the exhaust or use a prodcut like 3M Fire Wrap Duct Blanket ... we use it all the time on High Temp Duct and Boiler Breaching on large HP Boilers seems to have the proper temp rating ?

Home depo sells heat wrap for ductwork. It comes in various size rolls. It's about 1/8" thick. Mount it between the aluminum protector and the paint and you're good to go.This will create a thermal barrier between the plate and the paint.Use a hitemp adhesive to mount the barrier to the alum plate. The heat will never transfer through to the paint.

Thats interesting discussion because on my group 4, I have the exhaust pipes in the usual location but the paint in the engine bay just above those pipes gets very hot to the touch. I have always thought whether some type of heat material above the exhaust may help, but would think that would look kind of funky.

Thanks for the suggestions

My existing aluminum shield does a pretty good job of deflecting the heat from my headers. Additional insulation between the sheet metal and hood would be better but I’d really like to do is toss the aluminum shield and replace it with a stick on aluminized blanket or some other material that will do the job. I had to “adjust” two spots on the shield to make room for the snakes. The result was functional but looks like $#!+. I’ve also considered wrapping my headers but I don’t really have any experience with wrap either. Just thought I’d take a shot at throwing my dilemma out there and see what bounced back.

Why not a ceramic coating for your exhaust system?

Take a look at these products:

Might be something you can use. A couple of principles in thermal control is that the surface should be silvery and shiny. Brighter the better. This will help with radiated heat. There also need to be some air space that allows cooler air to circulate. This will help with conducted and convected heat.

My headers are already ceramic coated so that’s taken care of.

The heat shield link looks interesting.

I think I’ll just get samples and do some bench testing. A heat gun and an inferred gun to measure the difference between the products should do the trick. A great project for this winter.

With any luck I’ll get this sorted out and be sporting a “cool” look for next season.

Thanks to all, Chuck

Read the specs on this product, I would stick this to your alum sheild. It sticks very well so make sure you want it where you stick it...
