JohnD1956 Posted April 12, 2008 Share Posted April 12, 2008 Can anyone recommend a product or process to use on the cast iron exhaust manifolds. I don't want them to stand out, I just want them to look better than rusty metal for a car that will be used more than just for cruise in's, but not daily driving.

Pete Phillips Posted April 12, 2008 Share Posted April 12, 2008 John,I use that same stuff from Eastwood. It comes in cans and is almost like a paste. Rather than a brush, I put it on with an old piece of cloth, rubbing it on.Pete PhillipsBCA #7338 Link to comment Share on other sites More sharing options...
ice man Posted April 12, 2008 Share Posted April 12, 2008 John:I've had excellent results using plain old stove polish. There is a petrolum based one well as a water based product. I can only vouge for the petrolum based one as that is what I used. It lasts a long time at engine temperatures, and if it needs to be spruced up, just apply more with a rag or brush before you show the car. I purchased mine at the local hardware store.

JohnD1956 Posted April 13, 2008 Author Share Posted April 13, 2008 Thanks guys. tom, I will forgo the stove polish only because if they did need a touchup later, there is very little room to get your hand in there. But I may try that on my 56. Link to comment Share on other sites More sharing options...
RocketDude Posted April 14, 2008 Share Posted April 14, 2008 http://www.calyxmanifold.com/ Nothing else like it. I think Eastwood sells it, but this is mfg direct. Try it, you'll like it..! Cheap, and great..! Link to comment Share on other sites More sharing options...
Guest imported_Matt M, PA Posted April 14, 2008 Share Posted April 14, 2008 Calyx is like a paste. I used to use it, but grew tired of it getting all over me when working around the car.I started using the Hirsch manifold "paint". Works great, lasts well...you just need to blast of otherwise clean the manifold first. For what it's worth, I use the version that brushes on.

Guest martylum Posted April 14, 2008 Share Posted April 14, 2008 Over the years I've tried various spray on manifold paint with temp ratings from 800 degrees up and none seemed to last a very long time under regular driving operation. This is with an application on a carefully glass beaded manifold set and a primer if recommended.I'd go for a ceramic coating if you want a long-lasting finish.Various vendors advertise this service in various colors including a raw casting color. It's more costly than the home painted approach but well worth it if you want a permanent finish.Just had a 36 Lincoln's manifolds recoated in the same black ceramic coating they were done with originally and they seem to be holdng up very nicely. the original 1936 coating was almost entirely intact after 70,000 miles but had changed to a greenish color from the original black.Martin Lum Link to comment Share on other sites More sharing options...
Guest JDHolmes Posted April 17, 2008 Share Posted April 17, 2008 Hirsch manifold paint is my vote. Easy application, no muss, no fuss. Link to comment Share on other sites More sharing options...
Bhigdog Posted April 17, 2008 Share Posted April 17, 2008 I can tell you what didn't work so good. I tried POR 15 manifold restoration kit. Did EXACTLY as instructed. The stuff blistered and peeled off in little time. I ended up having to pull the manifolds and rebead blast to get the stuff off. They refunded my money but I was still pretty unhappy.......Bob Link to comment Share on other sites More sharing options...
Matt Harwood Posted April 18, 2008 Share Posted April 18, 2008 I've used Jet-Hot in the past on a variety of applications. Their ceramic coatings are permanent, indestructible and they have a cast-iron gray that looks very authentic. I'm going to have the Century's exhaust manifolds done by them as soon as I have the cracks repaired. Expensive, but you'll never have to touch them again and they'll always look new, plus there is some insulation value to protect against heat soak as well.www.jet-hot.com(Not affiliated, just a very satisfied customer).
