Any suggestions on what to use on manifolds.. will anything hold up?
I am leaning towards a dark gray.
 
Oh geeze, where am I going to find that? I prefer not to leave town any more than I have to.. lol..
 
You know I do have to admit that I used that on a triumph I restored years ago, I saw it about 3yrs after and it still looked good.. Downside is that I have no idea how much it had been driven at that point. I was debating using that. Maybe it would be a good test, if it burns off this is the one i'd want it to burn off of.. And the grey is the shade I want..
I just hate to buy anything por15.

Has anybody else had experience with this?
 
yea...i cringe at anything that says por 15...but from what i've seen this is good. Eastwood has a manifold paint like it also....and is probably just relabeled por15 like the rest of their products. i believe applying it with a foam brush is key. really gets down in the pores of the metal.
 
i bought some stove paint from a place that restores old parlor stoves years ago. it is like black cast iron . may still have the can , i'll look. i'll smear river mud on my headers before i buy por15...... :)
 
more i think about this there was a product, cannot remember the name for the life of me, that we used on a MG restoration....it was good stuff also...i will have to look through some pics to see if i have any of the can.

I have never found a good manifold coating from Eastwood or anything in spray bomb. I have had better luck with powder coating them. I have the stuff to do it but it doesn't cost much to have it done. I also like the ceramic spray coating from www.caswellplating.com The great thing about the ceramic is the lower temperature on the manifold. Those two seem to hold up better for me.
 
My machinist does header coatings and also does valves and combustion chambers, headers run $100 to have them blasted with shot/coated/ad baked. It is a liquid that he sprays through a detail gun. I've heard it's holding up better than the JetHot coatings but I don't know what brand.
 
bob, its probably a ceramic coat he is spraying. its really the only thing that will hold up over the years and stay looking good. regular powder wont hold up over 450deg as well as anything in a rattle can. i can do it for you chad if you dont mind shipping them to me. they'll get blasted, coated and baked at around 600. really super durable. comes in an array of colors. if you dont want to do it, hok has their high heat black which is similar. you can get that as long as they haven't discontinued it. its almost the same thing. i have used it on header pipes and years later it still looks like new. its stays delicate until the part gets hot. the heat on the part causes the chem reaction then crosslinks.
 
I use a high temp powder that has worked great on everything except my 31' Buick. It runs manifold temps in excess of 650 degrees in certain spots on the manifold. Still looks OK but the extreme heat in that area kinda cooked it a little. Poor desgin with little flow allows the heat to back up. I'm building a header for it now and will be using the ceramic coating from Caswell. I've been using more of the ceramic coating as it holds the heat in which is a nice benefit for underhood temps.

Kinda leaning towards a brownish gray, can you do a color like that?
I really like the color of the por 15 manifold paint but i want it to last if possible. if not I won't really complain either, but i figure this is a good one to experiment on as I can watch it as time goes by.
 
I ended up just spraying with manifold paint, i was really tempted to send to jim, but i'll save that for a project i'm more worried about.
 
did you use the por-15 manifold paint - how has it held up

thanks Stephen
