Painted manifolds ?

[The Lodge]

Hi all,
Removed manifolds due to blowing and because my engine mounts were loose and perished, in fact on the near side the engine mount braket bolts to the engine were completely missing !!
My problem is ive started to clean the manifolds as they were a bit rusty, what is the best thing to do

1 Clean most of rust off and re fit

2 polish to a shiny finish

3 or use a high temp paint

I feel if i dont paint them they will rust very quickly.
If i paint them will the paint burn off in a week,

Thanks, Paul.

I have used Halfords very high temp paint and its still fine about 1000 miles later on my V8S.
I used the metallic black but its more of a graphite, but still looks good. You will need at least one tin per manifold, I did a couple of coats, it doesn't go that far.

Was that brush on ?

I tried some VHT spray paint on the S manifolds and it peeled off in no time, was later told by a biking friend it only sticks to new or sandblasted metal, NO amount of wire brushing is sufficient?

Bought some of this recently but not got around to trying it yet

Thanks for advice,
Has anyone used "black velvet" before its made by por15 which is good stuff

I see that link has two other products on the page, each rated for even higher temperature (760 deg c), one of which is actually called "Manifold Grey".

The Aluminium colour one sounds interesting ... not that you can actually see much of my manifolds.

Would this stuff also work on the Y-piece ?

Presumeably, the manifolds get hotter than the Y-piece?

I used the vht black stuff from ebay on my manifolds, y piece and exhausts over 18 months ago and the finish still looks superb. Before that i tried the brush on stuff from Halfrauds but the finish and colour were poor. HTH.

Got any pics?

As part of my general refurb I decided to paint my manifolds with the Halfords high temp 'aluminium' (grey) finish and followed the preparation advice:




It looked good, but I was concerned at how easy it could be removed from the surface, a fairly-gentle scrape with a fingernail exposed the metalwork underneath.

Further applications of the paint (on the assumption I hadn't applied enough in the first place) failed to stop this, so it was onto plan B: polishing them:


But of course that made the y-piece look awful up agains the manifolds, so back to the polishing:


And then I 'discovered' for the first time the feature of exhaust-wrapping....... having read the "for's" & "against's" I settled on Steve Heath's opinion and decided to wrap the manifold's only:

(I repainted the flange so that it matched the block).

They're back on the engine now and will be fired up this week!

How the hell did you get the Y piece to look like that!

I used an industrial high temp paint. Painted the full exhaust, y-piece, and manifolds. 3000 miles later and just the manifolds need touching up. Looks really good and approx £25 for 5 ltrs.

No its aerosol. I did have my manifolds shotblasted when I had the chassis done

Depressingly my engine bay is no where near that shiny & clean (or rust free!). One small thing, is you ARB bolt done up OK?

Short answer: elbow grease and a polishing regime! I'm on my iPhone, but if you'd like a detailed reply say so and I'll do it here.

I'd appreciate a detailed reply. That manifold looks fantastic.

Thanks in advance.

I think he means the anti-roll bar mount, facing the front, between chassis rail and fan, under the top hose.

Ah! Thanks for that: it is loose as the "ARB" (as I now know it!) is to be tightened once the wheels go on, as are some of the suspension bolts.
