Exhaust manifold painting

[5portsrock]

Hi, I've got a new lcb due to go on the car. Can anyone recommend a particular brand of paint? What sort of surface preparation did you use? Any to stay clear of? Thanks in advance, Fraser

I ordered a pair of Cooper free flows last year. I always send mine out to have the flanges ground to insure a flat mating surface. I failed to notice the center flange had not been ground to clear intake cross over tube. I did not notice till fitting. And to make things worse I had sent both out for ceramic coating. After grinding to clear I touched up with VHT high temp rattle can, cooked in stove at 500 degrees. Steve (CTR)

I've used simoniz hi temp in black and its.lasted OK on my 8 port, just painted my lcb with the same after binning the heat wrap.

The MoD use a Henkel Chemicals paint called SUNKORITE to paint machine gun barrels. The barrels have been known to get fairly warm at times. It's a fairly toxic spray-on paint that's oven cured. Mind you, it soon cures once you let rip!

That's what mine and my Commando down pipes are painted with. Makes commercial exhaust paint look like radiator warmth paint

I have a couple of multi cylinder 2 stokes, over the years I have used several different Very High Temperature paints now available at an advertised 650C and 800C (in my book such temperatures will have a glow to them) on exhausts/chambers which worked and lasted extremely well. Cannot recall or recommend any particular brands but a number come up on internet/e-bay. search.

My brother had a Suzuki similar to mine, he had a powder coating process on his exhausts by a firm local to us and they were brilliant.

Thanks for the replies. I LL get the pipes blasted and then paint with vht flameproof.

I’ve generally have all my manifolds ceramic coated which I think works well and long lasting.

I’ve had good experiences with Rust Oleums satin black stove paint. https://www.sprayster.com/product/rust- ... gJOLfD_BwE

I’ve used it on 2 stroke front pipes, manifolds and smokers and it’s held up admirably.

Tried two cans of this the other week, both cans failed after 3 seconds of painting.. wiped off with thinners and installed bare metal.

I quite like this stuff, I’ve been using it for years.
If it’s prepared properly it lasts, you can always pop a heat gun in the exhaust to warm it up before applying it (not to hot)

We use a company in Abingdon, Oxfordshire called Zircotec, we used them 15 years ago but the coating fell off & I refused to use them as their product warranty allowance was no good but we used them last year & now their product is vastly inproved, you can almost put your finger on the tubes whilst the engine is running, certainly can after a minute of turning the engine off. Will use on my Maniflow manifold after the engine is built later this spring

I got a quote from them. Depending on which coating it ranged between £550 and £800. Ouch

running my Min years ago at full chat most everywhere I burnt the paint on the bulkhead & it was uncomfortably warm in the car so I don't wish to make it any worse than it is now or when I get it up & running

You can fit an alloy heat deflector under the bonnet (similar to the Abingdon works cars) a lot cheaper than that. And yes at high speed, motorways long distance etc, a normal exhaust will be glowing.

that doesn't give a 10 to 20³ reduction in underbonnet temps though

But that heat is going somewhere........ It's the very nature of an engine being a heat machine

it comes harmless;y out of the exhaust pipe heating the planet

Not just motorways but A & B roads, came home from Sutton Coldfield one night 4 up & saw an indicated 7k with a 3.4 diff, nearly 115mph. Every night I would see more than 100mph on the way home from work.

Try Zircotec in Lancashire….. just had a Maniflow lcb and collector for around £300. Excellent to deal with .
