I'm having a hard time keeping rust from showing on my manifolds after I've coated them. I used VHT 1500 degree cast iron manifold coating, and it looks great for a while, then rust starts popping up again. I've blasted the manifolds and coated them right away, and that still doesn't seem to do the trick. Getting tired of yanking manifolds off. Anyone have any tips on how to keep that nice clean cast iron look? What's worked for you?

Here's a reference of what media is best for what it is used for.

As far as what types of high temp paints, I'm sure that many here can tell you what they felt works best for them for a long time. Prep is the most important of course to have it last long and not have rust reappear. Avoid touching them with your bare hands after blasting. I would personally shop Eastwoods high temp paint. After painting them, put in oven to bake the paint.

I used the Eastwood brush on high temp coating after bead blasting the manifolds. It holds up pretty good and have only had to touch them up once a year and it's been on for 5 years.

Wow TopCat! You got the answers for everything! I was just looking for a chart like that...... Thanks

Drop Top, this is another option..... I have not used it yet, but POR 15 seems to make good stuff.

Another option is high-heat powder coating and yes, the powder is specifically made for high heat and has held up OK for me. For a ballpark idea, the guy did them for $60 with him doing all the work. Of course there are other coatings too but ceramic doesn't look much like cast iron.

The POR15 Hemi orange engine paint kit turns yellow with any antifreeze so I hope the exhaust manifold coating is better.

Hey, guys, thanks for the quick response! I'll probably be taking the manifolds off when I install the tti exhaust system, hopefully in the next couple months, so at that time I'll be re-coating the manifolds. I'll be sure to look into all the great ideas suggested here. Thanks again!

Another option to look into would be to have them Jet-Hot coated.. They have 1300 degree cast iron grey coating that I am going to use shortly. Here is the info page if you would like to request a quote. They also sent me a video of the whole process. Hope that helps...
