EXHAUST MANIFOLDS/REFURB

[TJC46]

Hi guys started to clean and paint my exhaust manifolds,im using a aluminium silicone based paint that according to the manufacturer is good up to 1000 degrees im sure it will eventually burn off but it looks good for now. My question is this the manifold faces seem somewhat pitted and before removal they were both fine, no leaks etc. While i now have them both off is it worth getting these faces machined in some way? can this be done? im sure when reinstalled with new gaskets, everything should be ok,its just that it was such a pain in the a##e job to remove them, i dont want to be doing it again for a slight leak, thanks tom.

Looks fantastic, my exhaust is off the car at the moment and was wondering what to do about coating it. what is the paint called and what sort of preperation is required.

I lightly cleaned up the faces with a block and 80 grit, then used a smear of high temp flange sealant (Lockite 5920) with the gaskets to ensure no leaks.

I prepped the manifolds and exhaust using a cup wire brush,the type you fit onto a grinder, it takes a bit of effort but you eventually get back to shiney metal. I then wiped everything down using cellulose thinners. The paint i purchased from a company called STOKES they are based in sheffield there web address is rjstokes.co.uk click on the link ....industrial... and scroll till you come to high temp aluminium paint. Im in the process of stripping everything down at the mo in prep for a body off this winter so ill report on the paints durability some time next year.:

the manifold face should definitely be cleaned back completely, no trace of rust or the old gasket should remain, or else you'll be taking them off again pretty soon! i forgot to say, a vice and an angle grinder is your best bet to remove the crap left on your manifold, its a pity you've painted them already................
