Yes, recently had someone who solves a lot of my problems for me powder coat the exhaust manifold on their '29 Hudson and it looks fantastic.

I know dozens of muscle car guys who had their exhaust manifolds powder coated plain gray bare metal looking years ago and they still look like brand new. That stuff holds up.

And the guys are right, the porcelain treatment, if you're going to drive the car at all, is only going to last a few years. Mine was porcelainized back when they restored it 20 years ago but the car really wasn't driven much (only 300 miles in 20 years). I've put over 400 miles on it since August and that glossy finish is starting to spider web and crack already.

Attached photo showing ceramic coating on my 32. This is Cerakote done by a powder coat guy. You must remove all the porcelain coating in order for this to stick. It is a bit fragile but can be easily repaired by scuffing with 220 and recoat yourself. I suggest warming the manifold a bit as that seems to make the repair flow out better. This is a high temp coating and will stay looking the same over time. No one does porcelain like the original so forget that if you plan you use the car. Also note the carb linkage like your car should have, the fiberglass down pipe wrap, which will help with the heat on the passenger side of the car especially when it it hot ourside.
