Hi temp paint for exhaust manifold
« on: June 26, 2016, 07:34:21 PM »
Did a search for this but did not find info. Thinking about painting new exhaust manifolds with a hi temp paint. Is one better than another. Saw Eastwood has a product with mixed reviews or should I just leave them and let them surface rust?

I'd put something on 'new' manifolds...  I've used 'Calyx', which gets rubbed on and had to be redone periodically, and I've also used Eastwood's Stainless Steel Paint before.   It will be interesting (to me) to hear other's opinions.. :)

I used a high heat paint and primer from kbs. Motor heat helps cure it. Of course I haven't started it yet but tomorrow is promising!  They call it XTC, xtreme temperature coating

Don't waste your time with paint. I have had about (4) sets of exhaust manifolds Ceramic Coated and they look exactly the same as the day I picked them up from being coated. Before that, I tried paint with no success. It will run you a little over $200 but well worth it.

I like your idea even better, Dale..  IF the poster has a closeby powder/ceramic coater...   What color/etc did you have them put on your exhaust manifolds??   and does that preserve the 'new look' for the cast iron?

For the purist it might not be acceptable but with a 69 SS350 we owned I glass beaded and then used por-15. Its been on the car's original exhaust manifolds for 15 years and still looks great. Easy to use and obtain!

Stove Bright High Temperature Stove Paint
Charcoal

I have had success with paints, both Eastwoods & the one above, I glass bead and prep the manifold prior to painting and run them in slowly to set & cure. I have had some touch up also w/o real issues, I agree the above method is preferred and superior, however you CAN have success with paint, many many examples out there at a fraction of the price. Best option is to send them to a higher end restoration facility for a coating.

I used the Eastwood High Temp Coating Factory Gray, and it came out great.  This was about ten years ago, and my exhaust manifolds still look like new.  The trick is all in the prep.  I had them sand blasted, which I think is crucial to how they turn out.  The sand blaster guy charged me $20 and they were done in one day.  When I got them home, I cleaned them with lacquer thinner and a toothbrush, making sure to get in every corner, crack and crevice.  I then scrubbed them with Dawn dishwasher soap and water, and blew them dry with my compressor.   I then put them in my oven and heated them up to the max temp for 20 minutes. (I have one in my garage for powder baking, but you in house one will work fine as well, as long as the wife either approves, or never finds out about it).   The heating up was for the purpose of releasing all the oils and grease and dirt and crap from the pores of the cast metal.  After they cooled, I put three coats of the Eastwood High Temp Coating, let it dry overnight.  The next day, I put them in my oven and heated them to the max temp, which was 550 on my oven for 20 minutes. 

Again, this was ten years ago at least, and they still look great, and it cost me about $50 ($20 for sand blasting, $30 for Coating.)

I do my own ceramic coating.  Here is a set of headers that I done over a year ago and just had the car out yesterday and they still look the same as they did when I coated them.  Only problem is I am limited on colors.

This is called titanium.
