I bought a dc sports 4-1 header. has a little bit of rust. after i sand a little should i spray a coat of primer or just hit with high temp paint. thanks

 

Neither, get it ceramic coated professionally. The ceramic coating will lower heat emissions from the header and actually hold up over time to the heat. You can get ceramic coat in various colors such as grey, flat black, even a polished look.

It'll actually serve a purpose on top of looking good.

 

what is the price range. Tight on money, but if not to expensive will consider.

 

anyone else.

 

The paint will just start to bubble once the header gets hot.

 

VHT Fireproof paint works.

can i buy the paint at the local body shop or at something like walmart or something.

 

The professional coating is around $200; I had my header and downpipe done by HP Coatings. They cleaned up the header perfectly before coating; has held up great.

But, I understand the $$ issue; VHT will work fine, though I'd watch for rust to rear its ugly head again next spring. Coating would make sure that this wouldn't happen.

 

Just pick the correct paint and paint it, dont think you need primer, most will bubble with heat over time so choose carefully.

If you're worried about rust then I would be carefully scraping that too, would peel any coating of it over time.

 

I bought some paint at a store that sells wood stoves and fireplaces. I used it to paint my turbo manifold and its held up for 2 1/2 years. You will have to make sure you get ALL the old paint off before you repaint it. I sandblasted my manifold and then painted it. Still looks good

 

I can get coating done locally for around $100 for a header/exhaust mani in either flat black (2300F resistant), or a polished like finish (1800F resistant).

 

Sandblast the header b4 you paint it...
Most bodyshops or machine shops have them

 

One option is POR-20. It's a heat resistant paint that POR15 makes. Goes on easy on sandblasted metal, looks nice. Bakes on when the metal heats up.

 

I painted my DC header with high temp ceramic paint and it burned off the header as soon as I started the car. Not worth it IMO.

That had to suck to see the work you put into painting it go down the crapper in a matter of minutes...live and learn
