Sure you can but your car smells like a cook out everytime you start it. (kidding) I've doen it - I find that prep is key no matter which paint you use.
I have done it, holds up fairly well for a driver. I would not use it for a show car or anything. Another trick I have learned through the years is that not only do you prep them really well, but once they are ready to paint, put them in the oven at 400 degrees for about 45 min (send your wife or GF to the mall with a hundred dollar bill) and then paint them before they cool. Something about painting them hot lets them cure out completely different.
BBQ silver on the headers, BBQ black on the down pipes to hide them. 2,000 miles I touched them up and this is after another 3,000
I Live In Ny Drive My 31 To Work -everywhere Open Hood Sometimes It Sits Out In The Rain At Work And Sears Bbq Paint Works As Good Or Better Than Vht On My Headers Ive Got 19 Years On Them Tim
With regards to prep I was going to use metal clean then let them dry and spray away. I was also going to try and get as much inside as I could. I'd try the oven trick, but they're at my parents house. I know that won't go over there. Thanks
Is the BBQ paint rated for higher temperatures? I think I used an exhaust paint that claimed 1500 degrees...maybe I got that wrong.
