Paint for Exhaust Manifold

Sat Aug 07, 2004 2:07 pm

The exhaust manifold on my '48 cub was very rusted. So, I took it off, removed all the rust and primed it. Now I am thinking about painting it black (as I have seen many other cub owners do) and wondered if anyone had a recommendation of the correct paint I should purchase for this job. :)

Tom, you might consider getting your manifold powder coated for a great looking appearance. If not, a good high temperature paint will last a little longer than standard paint.

Powder Coat it RED?

I used Dupli-Color (High~Heat) silver. It has ceramic in the paint and it states that it withstands intermittent temperatures up to 1200-F. I painted mine and baked it at 400-F for an hour.

If you use high heat paint dont primer the manifold first or the primer will burn off and take the finish coat with it.

Red, black or silver or any other color of your choice actually. If you were looking for originality, then red would be correct.

I have had three manifolds powder coated with high temp black powder. They turned out really nice and will not rust. I use Joey's Powder Coating...he is listed in the restoration links.

If you are going to paint it, start with very clean metal and paint with a high temp paint. If the primer you used is not intended for hot surfaces, it will burn off...and so will the paint. When I painted the manifold on John's Missy, I had a friend media blast it clean, then I applied several coats of high temp black. I am anxious to see it at the Cub-Arama and see how it is holding up.

Does powder coating fill in the rust pits?

Mike, The powder coating will not fill the pits in the metal. But there are some metalized materials that can be used to fill the pits before the powder is applied. Steve

Personally I think the pits or as in mine (Dimpled-Surface) gives it character and looks good after it is painted. But then again to each his own. :mrgreen:
