I was wondering if this stuff is any good?
I have a RKS 4-1 ceramic coated header.... And my under hood temps get rather toasty... So i am just looking into ways to decrease the engine bay temps..... this sounded like a good start.... but for $50 or so...i want to make sure it will help a bit at least.
It will void the warranty on the header, since it will gather and hold water against the header. It causes the header to rust fast, but other than that it works....
yeah, don't use the stuff. it's nasty. you can't do much more to the header other than coating it, which you already have.
the best way to decrease your underhood temps would be to get the downpipe coated, and go with some sort of vented hood, like the extractor hood.
