Exhaust Manifold Paint
I'm about to repaint my exhaust manifold. I got some MG-69 manifold dressing.
Do I need to sandblast the manifolds first? Is that even possible? - It is a special paint I guess. The exisitng paint is not that bad but could be better... What about coating?
Please advice, thanks.

Calyx never completely dries and will rub off on anything that touches it.
I prefer a painted solution rather than a "dressing" for that reason.
Here are the manifolds I did off my '78 with Eastwoods Factory Gray hi-temp manifold paint.
You can get in in a spray can or small can to brush on. I brush it on.
The manifolds themselves I did with the Factory Gray than did the A.I.R. tubes with basic black.
did these 2 years ago and they still look the same today

Calyx is good stuff...particularly for the person who doesn't want to remove the manifolds from the engine. If yours are already out, you can clean them up much better and apply a more permanent coating. I use Calyx and it does look like fresh cast-iron; but I have to touch it up every now and then. A good high-temp coating might be preferable....it's really up to what you want for your car.

They look about the same as the painted ones shown above...at least, right after you do them. They'll stay that way for some time, but areas will eventually flake off and you'll need to touch them up. Still, a pretty good alternative to removing them and getting them coated.

I have used POR-15 heat resistant paint "factory manifold gray" available from TIP tools for $18 on at least 5 sets of factory exhaust manifolds and they have held up great. One small can will do at least 3 sets. The first one I coated was about 6years ago and still looks great. The best result is after blasting. The brush strokes disapear after the first heat. The cheap dressing will not last.

Will 8 oz be enough to paint a pair of BB manifolds?

I wanted a permanent fix. I had the manifolds sandblasted and coated inside and out with aluminum. Looks like clean, flat silver. No more flaking, rust or greasy residue. Check out your yellow pages for a local sandblasting and coating company and go see what they can do. Jim

Do you think this is the same as what's sold through Ecklers?

I use it on my manifolds and got enough for a set of headers. Still have some left.
