I want to set my 451 in saturday.I wrapped th headers in that copper embedded wrap but forgot to buy that paint or what ever it is that sets it.
Is anything available off the shelf that would work?I dont want to wait another weekend to do this.My fault but thought i would come visit you racers(wish i was) and see what you guys do thanks alot.

I could see that over time but by time that happens i'd be ready for new pipes,these are cheap but very heavy.
Anybody else?

Your better off getting the headers coated.. I dont like the header rap stuff because I see it rusting all the time(unless your pipes are already chrome or plated, then it last longer, which then I wouldnt be running a rap any how)... the coating helps hold the temp in but after time they all let the heat transfer

To answer your question, you can use whatever header paint you want to color the wrap. Problem is, some of the wraps suggest soaking the wrap in water to get it more pliable to install, so you don't get hot spots where the wrap isn't touching the pipe, and the paint won't stick to the wet wrap, so you have to wrap header, install, start engine to fully cook the wrap, and remove to paint. That may be where some of the rust issues start, also. The pipes should already have a good coating of paint on them before they are wrapped, but there again, to set the header paint usually requires an install and heat cycle to set the paint.
On another note, I don't personally care for the wraps, especially on mild steel pipes, because the heat goes through the pipe, then is reflected back into the pipe, and the pipe material itself sees higher temps than an unwrapped or a coated pipe. Many times this overheats the pipe, making it brittle and prone to cracks. I've had to replace 1 year old headers because they cracked right at the top of the tube by the head. A good coated pipe, say Jet Hot just as an example, is coated inside and out. The inside coating stops the heat before it gets to the pipe, and provides a thermal barrier so that the pipe never sees the high temps and/or the brittle condition.
I hope this gives ya a little info to help ya decide to wrap or coat.

Yeah, the idea is to keep the heat inside the pipe, and there have been times we even had to re-jet the carb because the headers scavenged differently.
As to the paint, if you just fog the wrap enough to give it an even color, it doesn't change the amount of "air pockets" enough to ruin it's effeciency.
Where I used to work, they did a lot of vintage race cars, and it was common for cars of that era to wrap the pipes. Often we would just have the insides ceramic coated, leaving the outsides bare, and use the wrap for looks. The inner coating blocked the heat from getting into the pipe metal, and the wrap got the look they were after. These headers were usually stainless, so rust wasn't an issue.

Blah blah blah...... . .
Hey dodge ... just go get some decent header paint and paint em...
it helps keep water/motor oil out of the fabric. and helps keep the material from freying... (its like pantyhose.).once you knick the fabric it will pull and run and come apart over time at that spot... Paint helps it stay together a little better. I use vht silver header paint. works fine...I have TTI's wrapped since 04. no rust, less heat when pulling plugs(dragrace) the only thing i dont like about it is..ITCHEY working with it. Ill continue to wrap all my drag headers fwiw.
you guys go ahead and biotch now...
