I totally agree with what Richard Tucker says. I did
my own ceramic coating using Techline Black Satin.
During the preperation I kept wondering how the hell
some listers get the insides of the hot housing, manifold
coated without flaking. To etch the surface properly, you
must blast the object at a perpendicular angle. Blasting
into a pipe or turbine housing would entail the need to blast
the surface at a very very shallow angle. The problem that
arises from this is that the etch pattern will not be optimum
for the coating to stick on & that's the reason why flaking
occurs. Unless Swain uses a different method of coating,
I would advice against coating the internal of pipes, hot
housing etc.

I have had the thermal wrap on my crossover and downpipe along with the blanket wraped on both sides of the turbo for over 13 years. Never had a problem with anything. It is a very good product. The new black color is more rugged than the original white. I believe the insulating properties are better than that of ceramic coatings, it just is not as hi-tech looking.

it seems like it would not be that hard to design an attachment to go perpindicular in pipes, so long as they are straight. Just make a long wand with a 360* circumferential spray head. You could make a flexible wand with guide-rollers for lightly bent pipes....

So you guys think that ceramic on the outside of the pipes then those blankets are the best way to go? What about the crossover pipe, should I wrap that with a blanket as well?

I had some other questions to ask but im drawing a big zero right now, ill try to remember them and post later tonight

Patrat,
I thought about that as well. Even if you could solve the
problem for blasting, you'll have a problem when applying
the coating. The reason being that it requires a constant
thin layer to be applied. If you can't control the over & under
spraying, the coating will for sure flake. BTW it would be very
difficult to design a gravity type spray gun for close proximity
application.

Brian: There is a company that sells the ceramic coating stuff. You could apply it yourself and either leave it to air dry or bake it. JChen tried it and ended up baking it since air-drying wasn't good enough.

I have the cross over and downpipe wrapped, it's great and does the job properly. This week i would probably wrap the headers as well........

Wrap the down pipe from the turbo and crossover. The blanket is for the turbo and exhaust manifold. If you had headers wrap them instead of the blanket....

Personally I don't feel comfortable wrapping the exhaust
manifold. Reason being that on cylinder 1 theres the accordian
joint which is rather thin as compared to the other 3 exhaust
pipes. If you wrap it up yes it would keep the heat in which
is a good thing but the temperature would be so much higher
that it may cause cracks especially on the accordian joint as we
do not know what temperature the exhaust manifold can withstand.
