swordfish210 20 Posted July 25, 2009 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 Share this post Link to post Share on other sites
ablister 31 Posted July 26, 2009 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 Share this post Link to post Share on other sites
swordfish210 20 Posted July 26, 2009 VHT=Very High Temperature. Plus it's a TU engine so it's right out the front. Share this post Link to post Share on other sites
EdCherry 34 1 Cars Posted July 26, 2009 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... Share this post Link to post Share on other sites
swordfish210 20 Posted July 26, 2009 Duncan has some... I bet i'll lose a couple of fingers trying to get it from him though Share this post Link to post Share on other sites

swordfish210 20 Posted July 26, 2009 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. Share this post Link to post Share on other sites
miamichris 9 Posted July 26, 2009 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! Share this post Link to post Share on other sites
GLPoomobile 958 Posted July 26, 2009 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. Share this post Link to post Share on other sites
swordfish210 20 Posted July 26, 2009 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 Share this post Link to post Share on other sites
Redtop 14 2 Cars Posted July 26, 2009 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? Share this post Link to post Share on other sites
swordfish210 20 Posted July 26, 2009 Thanks. No it's not the standard manifold, it's this one: Share this post Link to post Share on other sites
johnnyboy666 195 1 Cars Posted July 27, 2009 my 4 branch has the little bolt welded on so you can use the heatsheild if you want to hide it a bit Share this post Link to post Share on other sites
swordfish210 20 Posted July 27, 2009 Mine did but i cut it off, why would i want to hide it under some skanky heatshield. Share this post Link to post Share on other sites
welshpug 1,627 Posted July 27, 2009 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) Share this post Link to post Share on other sites
