Restoration

For years restorers were at a loss about what to do with cast-iron exhaust manifolds. A few restorers of large, expensive classic cars would send their manifolds out to be coated with porcelain. Although they looked great all smooth and glossy, the porcelain was prone to chipping and, frankly, didn't look factory correct. Many others took the budget approach and simply painted their manifolds with high-temp spray paint. However, the colors never looked natural and the paint didn't last long before the rust started to show through.


A few years ago The Eastwood Company introduced its cast-iron color, Factory Gray High Temp Coating, and restored engine compartments have never looked better. It resists heat up to 1,200 degrees F and maintains a foundry-fresh, gray cast-iron appearance. Best of all, it's reasonably priced and easy to apply in your own garage with nothing more than a wire brush and a paint brush. We've used Eastwood's High Temp Coating ever since it was introduced and are always amazed how well it works.


For photo illustration purposes, we prepped a set of small-block Chevy "rams horn" exhaust manifolds just to show how quick and easy it really is. Eastwood also claims that it works equally well on mild-steel-tube exhaust headers. We will put it to the test on a set of tube headers in the very near future.

This set of OE cast iron exhaust manifolds is in fairly good condition. However, rust and burned on oil residue can make an otherwise sanitary engine compartment look rank.

The first step in the Eastwood High Temp Coating process is to get the manifolds as clean and rust-free as possible. The best method is to glass bead or sandblast or they can be wire-brushed and dipped in Eastwood's OxiSolv Rust Remover.

Fresh out of the blast cabinet, the oxidation (rust) process begins, so be ready to apply the High Temp Coating as soon as possible.

Just prior to applying the High Temp Coating, we sprayed the manifolds with Eastwood's PRE paint prep to remove any silicones or grease that may have gotten on them. Lacquer thinner works well for this step too.

The Eastwood High Temp Coating can be applied with a foam or bristle brush. One medium coat is best. The coating will fully dry overnight. The manifolds should be installed within a week and the engine should run for at least 20 minutes to bake the coating on.

The finished product has a great as-cast look. Future touch-ups are possible if something should get on the manifolds and stain them. During the first 20-minute curing time with the engine running, make certain there is adequate ventilation.
