From the headers back.

Parts of the system have a bit of rust showing. Has anyone tried spraying Rust-oleum Rust Reformer prior to painting with a paint designed for high temperatures?

Thanks
 
I had mine out a while back and wire brushed it, sprayed rust converter all over it (the stuff you let sit on it overnight that turns it black), then used the Rustoloeum silver high temp barbeque grill spray. This has held up better than the silver VHT hi temp stuff I used last time.
 
used rustóleum bbq black paint rated 750ºC
no preparing layer before only brushed it and rust converter too
as to the exhaust manifolds i prepared them before in a bath of hydrogen chloride, this removes all the rust, but you must clean later with wáter so rust converter is a must
 
I had my headers ceramic coated.

Exhaust is just steel right now although I am going to have a guy build a custom SS exhaust for me soon.

I have a can of that Rust-Oleum Rust Reformer. It says do not spray on anything that gets over 200 degrees F. How is your work holding up Steve?
 
I used the spray paint stuff you get at the local car part store. I think it looks ok.

To protect the environment I always make sure a can is fully used rather than end up contaminating or poisoning some poor species. To that end I solicit the board what to apply any leftover paint or chemical to.
 
Extra coats on your headers are the first thing I thought of.

A coat or three on the (exterior only) of your BBQ.

Gift to another coupe owner in your neighborhood.

Proper disposal as hazmat, after "deflating" the can.
 
POR15 - High Temp

Stan, you might consider using the POR-15 44216 Factory Manifold Gray High Temp Paint - 1400 Degrees. It is available in three colors.

I just buy my POR15 items on eBay with free ship or you can go directly to the POR15 website. I have had very good results with using their products other than getting that stuff off your hands.

The POR-15 website at http://www.por15.com/High-Temperature-Paints_c_10.html says that Factory Manifold Gray, Black Velvet and POR-20 have all been replaced by POR-15 High Temp Paint, available in Flat Black, Factory Gray, and Aluminum colors which you can see at http://www.por15.com/HIGH-TEMP_p_104.html

It ain't cheap, nor even inexpensive: 8 oz. can $19.50 (probably all one exhaust needs?), 15 oz spray $24.60

Degreasing and mechanical abrasion are the recommended preparations.
 
exhausting

Hi,

I have used trhe POR 15 exhaust manifld grey on a few different cars on the headers, looks great, flows on not too bad and really stands up well but I sandblasted and metal prepped the headers before using the POR 15. I have used all of their products in different area s of the car and they certainly stand up to their reputation. WQe even ceramic coated a set of early Jag headers once and after 3 months , they looked like s**t but where we used the POR 15, it still looked great

My 1 cent s worth ( inflation )

Thanks, Rick
