Painting Exhaust manifolds?

Recommended Posts

I used POR15 manifold gray paint. I brushed it on 2 years ago, still looks good.

So My engine is out for the trans rebuild and I am painting the engine. What do you guys use for painting the exhaust manifolds if anything?

 

Scott, there is a product you rub in the exhaust manifold to keep the color right. I’ll send the name of the stuff in a pm.

Calyx (KAY-licks) manifold dressing.  The really nice thing is the way it's applied and it's easily touched up if needed.  Google the name to find their website and dealers.  Pictures tomorrow when there's some natural light.

VHT just came out with cast iron gray high temp. I used it on a set of freshly blasted manifolds and it looks great. Only been through a couple heat cycles and still looks fresh. Wish they would have made this stuff years ago.

Gents, Calyx ( Ed, thanks for the name ) exhaust manifold dressing is applied so hopefully you don't have a mess in the application. You can put the stuff on with your finger(s). I got my 3 oz. at Eastwood. I might say Eastwood is a good supplier for stuff you use to "dress up" your car. They ship fast and the products Ive purchased from Eastwood have been first class. I don't own stock in Eastwood. The plug is because Eastwood has good products.

IIRC, Eastwood notes that Calyx is not as durable as some of their other coatings.  In light of that, what is the advantage of using it rather than a more durable coating if the manifolds are out of the car and there are (presumably) no application issues?

Cant beat that, does it smudge ?

As I said back in post #5, if it's easy to touch up if needed.  In place, on the car, with the engine cold or hot.

Well sure.  Would you rather sell one of your own products or one for which you're just a distributor.   Think $$$$$$$$

 

Most of the problems I've read about are the results of poorly prepped material.  Taking a wire brush to the cast iron probably still leaves a goodly amount of iron oxide in the iron.  If you're manifold is off the car and you blast it before coating it, you probably won't have any problems.  The manifolds that I pictures were Calyx coated about three years ago.  They've never been on a running engine but heat cures them better than just air.  I did sand blast these before coating them.  They've been on a shelf in the garage since I coated them.  These are for a '63, you can tell by the boss and bolt in the passengers side that the dip stick tube bolts to.

               All of the brush on coatings on manifolds don't last but 3 years or so and they fail and rust everywhere. What I do

on my serious frame off resto cars is have them jet hot coated, which lasts forever.  My Riviera currently has rusty manifolds and they are going

to stay that way....it is absolutely correct and zero maintenance. I've tried all the coatings other than the jet hot and they don't last

and are a PITA to maintain.

To me, the patina of rusty cast iron exhaust manifolds looks much more natural than any painted or ceramic coated versions !

I'm with Seafoam65 n that topic !
