Spray on internal header coating?

[jakemccarthy]

So I was reading a car magazine and I came across this spray that is supposed to lower under hood temperatures. Do you think it is worth anything?

Being from Eastwood, it should be quality stuff. But, why do you need to lower underhood temps, especially where you are. I personally don't think all the work will be worthwhile. You can't just pull the manifolds and spray the coating inside. You will have to clean them first. IMHO.

I have heard good things about the company but this is a new product to me. Don't know anything about it but will do some homework, now.

Glad you posted, I'm storing this away for later consideration when I am rebuilding my car's engine.

Well I wouldn't bother until I buy some better headers. And believe it or not our summers are hot as hell at times, and at some point I am going to end up in South Carolina.
