Vht Paint

[swordfish210 20]

Whilst I have my exhaust manifold off I was thinking of giving it a coat of paint as it's looking a bit manky. Has anyone any experience with VHT paint or am I better off saving my money?

 

Thanks. Mark

don't think it will work on an exhaust manifold as they can get very hot plus noone will see it as it'll be tucked down the back

VHT=Very High Temperature. Plus it's a TU engine so it's right out the front.

Anywhere else im sure it would be fine, but on the manifold im not to sure... I guess theres only one way to find out Duncan has some...

[swordfish210 20]

Duncan has some...

 

I bet i'll lose a couple of fingers trying to get it from him though

What he doesn't know wont hurt.

i know what vht stands for but do you know how hot the manifold can get...?

[swordfish210 20]

Yes actually. However the Hycote stuff says that it will burn off at about 500 celcius, a cack site less than my manifold heats up too. I just wanted to know if anyone had used it before with a good result.

I've used it on my gti's manifold when I rebuilt the engine..but the engines still on the stand and waiting on the shell coming back from being painted! so not much use to you mate but I reckon its worth a go!

I've used Halfords silver VHT paint on an XU 8v manifold before. It was fine, but did sort of flake off a bit becuase the surface wasn't teh best to start off with. I did try to clean it up before I painted it but you know how horrible these cast manifolds get when they are old and corroded.

 

I'd say if you have a properly clean and reasonably smooth surface it'll be OK.

[swordfish210 20]

So it works if you do a good prep on the surface. I reckon i'll get a can of Black and have a bash at it then

The halfords black satin is the best vht ive used yet, and im no Halfords fan. Just apply it in thin coats and build it up with a few coats. Thats how I got the best results, and I also had the manifolds that I did bead blasted before hand. There is some rust starting to come through on one after being done 1 1/2 years but it's not bad. That was a mk2 escort The only way to get a colour to stick to a manifold is the company zircote iirc and that is a complete fortune to get done!!

On another note, do you not have the wee polished heatshield over your manifold if it's a tu engine?

[swordfish210 20]

Thanks. No it's not the standard manifold, it's this one:

my 4 branch has the little bolt welded on so you can use the heatsheild if you want to hide it a bit

[swordfish210 20]

Mine did but i cut it off, why would i want to hide it under some skanky heatshield.

should be perfectly Fine Mark, there's stuff out there specifically made for manifolds and will take up to 1500 degrees (can't remember if that's C or F but more than enough)
