I just had my exhaust manifold glass-bead blasted and would like to put a high-temp paint or coating on it to prevent rust. Is there some easy & effective treatment I can apply myself, or would it be better to have it professionally done? Thanks for all replies.

Eastwood's seams to hold up better than most.

Probably not the best thing out there, but I blasted mine with aluminum oxide and then painted them with stove black...

DIY, Rust.

You should try a ceramic coating - you can do it yourself (it sprays or brushes on) and withstands 2000F. There are several places that sell a variety of colors (cast iron, black, flat, white, chrome, blue, etc.). Although I have yet to use this - I plan to. Here is a place I found where you can buy the supplies: Columbia Coatings

Just go to the Ceramic section. I am sure there are other places out there that sell this stuff.

You may have an issue with your glass beading - might not give sufficient "bite" for the paint to adhere too.

I've had good luck with Eastwood's coating... make sure you don't skimp on prep work. I had mine sandblasted and then sprayed with a cleaner (can't recall the name, but it was similar to brake cleaner....nasty stuff).

i have not done this myself
but had this older article as a bookmark:

I used VHT manifold paint and it works pretty good.

I used eastwoods over 2 years ago and I drive this car regularly. Has held up very well. I did have them blasted first.

There is one very small spot where I see rust coming through. but it's so small and has not spread. Im thinking about sanding it down and touching it up.

Mine still look good .... I used the eastwood coating about 14 years ago

Another vote for eastwoods. Mine is holding for 12+ years.

I'm very happy with the results I got from POR 15 exhaust coating. I have about 2000 miles on mine and they look much better than my friend's manifolds with the Eastwood stuff on them, but I don't know if he did the prep work correctly. I'll try to remember to post a pic tomorrow.

Results will be much much better on a beefy iron manifold than a set of tube headers. I have found the BBQ paints hold up as well as the VHT stuff on exhaust parts.
