Need some help here, I used POR15 manifold paint on my Skylark exhaust manifolds and it worked great but what I need to know is if anyone has tried it on headers and if so how did it do, I bought some new headers for my Shelby Dakota and I know the finish that came on them is gonna burn off in a matter of minutes so I want to address it now before I install them.
Went on the POR15 web page just now and they have a higher temp stuff that says its for headers...POR-20, anyone tryed this?
I used the Eastwood manifold gray on my TA 350 headers.I wasn't that impressed.It says to have the engine up to temp and it will seal itself by bonding to the metal.I broke my motor in and have run it for a few times to get it up to temp but I am starting to see surface rust.On the other hand,it really doesn't say its for header use.I painted mine about 1 1/2 years ago but its never been driven on the street yet.
Ditto on the Eastwood product. Sandblasted my manifolds and painted them exactly as directed. Surface rust appeared within a year. And, the car is kept in a dehumidified garage. Would not recommend.
Long lasting and paint is an oxymoron. HPC ceramic coating and forget about it for the next 10 years. "Cheaper is usually more expensive in the long run"
AMEN...I don't understand why anyone would use anything but a ceramic coating on headers. Most places have several colors to choose from if you don't like the chrome/aluminum finish. Sure it costs more now, but they last forever.
Thanks man, I figured it would be good, I have alot of faith in POR15 products and the Black Velvet exhaust paint I used on my Skylark last year looks as good right now as it did an hour after I sprayed it.....I'll be in the blast cabnet tomorrow after work getting these headers ready. Thanks again :TU:
The secret with the high temp manifold paint is to heat up the manifold this is to remove any condensetion form the metal. I had my manifolds off the car when I painted with the dull gray Hirsch paint. I used my small propane tourch to heat the manifold first, just hot to the touch and them painted them. This was 7 years ago and paint is still holding, darkened in color a little. Some restorers I know would put manifolds in wifes oven, when shes not home, and get them really hot. And them paint them, use her oven mitts to remove. Jim Schlf palbuick
jim: i too used hirsch manifold paint , only i stuck the manifolds in an oven & heated them up before applying the paint. still look great .
