mazfg Posted January 15, 2013 Share Posted January 15, 2013 Having now taken off my exhaust manifold and seeing the brown rough rusty appearance it has..... I'd like to clean up, wire brush it and paint it black. Would this stuff do the job: http://www.ebay.co.uk/itm/Matt-Black-stove-exhaust-ovens-HEAT-RESISTANT-SPRAY-PAINT-Everbuild-Purimachos-/160727730035?pt=UK_Home_Garden_Other_Fireplaces&hash=item256c1e8773Is a spray better or would it be better to brush it on?

Stu 1986 Posted January 15, 2013 Share Posted January 15, 2013 I've heard BBQ paint is good for such things. That comes in a range of colours too. :) Quote Link to comment Share on other sites More sharing options...

Paudman Posted January 16, 2013 Share Posted January 16, 2013 http://www.ebay.co.uk/itm/PJ1-MOTORCYCLE-HIGH-HEAT-EXHAUST-PAINT-FLAT-BLACK-11OZ-/110683323052PJ1 is used by motorcyclists on bike exhausts, I've used it for years on Triumph cars too. There should be a local stockist near you or buy online. Quote Link to comment Share on other sites More sharing options...
ferny Posted January 16, 2013 Share Posted January 16, 2013 Whatever you use, use it properly (fully instructions exactly) and make sure it can stand up to 1500°C. But even then it may not work as all the paint I've used on the Acclaim and Herald burnt off quickly. Quote Link to comment Share on other sites More sharing options...
Jezmond Posted January 17, 2013 Share Posted January 17, 2013 You could always have it ceramic coated by Zircotec. It'll be permanent and will help with temperature management. Quote Link to comment Share on other sites More sharing options...

This technique is presuming you are going to paint the manifold whilst it is off the engine.Remember this technique will get the Manifold very HOT so be sure to let it COOL down properly before handlingHope this helps.Alan.

James Posted January 19, 2013 Share Posted January 19, 2013 I got my mild steel tubular manifold coated in an aluminium stuff they use on aircraft exhausts (I think) — seems to have stuck well in the 9 months. Quote Link to comment Share on other sites More sharing options...
JohnD Posted January 19, 2013 Share Posted January 19, 2013 The tins of so-called exhaust paint usually say, in very,very samll print that it should be aplied to 'bright metal' In other words totally lacking in rust. Certainly my experience of near obsessive cleaning and wire-brushing doesn't keep the the paint on for more than a year.Commercial surface treatment systems, as James has used my be more successful, but I've givben uip on manifold painting as a waste of money.John Quote Link to comment Share on other sites More sharing options...
James Posted January 19, 2013 Share Posted January 19, 2013 John — they blasted mine and then immediately sprayed it in what I assume is very hot aluminium powder.It's been on the car and done several thousand miles now — and it's still there and hasn't discoloured.Hopefully a good sign that it'll stay there for a reasonable amount of time!
