Stan:
I used VHT flat aluminum header coating (it is not a paint) good
for 1400F. Picked it up at the local auto parts store. I bead blasted
and then solvent cleaned the manifold going on 3 years now and no
problems - although I only put a few thousand miles a year on the car.
Still, I am impressed as I expected the stuff to disappear in a cloud of
smoke in a few minutes.
It goes on very soft, and is easily scratched, but the first
time you fire the motor it fuses on and is surprisingly tough after
that. I am guessing it has some sort of low temperature glass in a
slurry. The glass fuses when it gets hot enough?
There are also some coatings from Eastwood (?) that you might
consider. You can get a cast iron grey coating that preserves the
original appearance (before it got rusty, that is).
The VHT is cheap and so easy I would not advise you to give up.
If you want something easy, give it a try.
The ultimate is a Jet Hot coating, but that is expensive and you
need to take your manifold to a business that does it. It is the best
however. I had jet hot coated headers on my Z28 Camaro, and they looked
brand new 5 years later. Awesome stuff. Very pretty, too.
YMMV,
Vance

Subject: [6pack] Exhaust manifold finishing
I did some research this morning into high temp manifold paint and cast
iron
manifolds. The consensus seems to be that these finishes will work for a
while
but eventually it will either peel off or rust will eventually
re-appear.
Does anyone have a good story here using paint or should I just give it
up and
stick with the rusty cast iron ?.
Stan
