I am wrapping my headers and am wondering if I can use header paint to seal the wrap instead of silicone Spay?

Question

I found a video clip that recommended a silicone type header wrap spray to keep the wrap from becoming water logged and holding water directly on the header increasing chances of rusting when inclement weather hits or in case I go Mud Bogging in my truck. And then I got to thinking why wouldn't high temp header paint work in its stead? Anyone know if this would work out ok?

Answer 1

Look it sounds to me your trying to prevent your header from rusting. That almost impossible. The best way to go is with ceramic coated or stainless steel . Even paint brake down over a period of time. As well silicone has its braking point to but you say you may go mud bogging .

Rap is usually for heat prevention because heaters produce allot of heat that cause the car or cab to get hot. If this is the case your are using this for then I would go with what the product recommends. Paint my headers first thoroughly with a High Temp Paint. Then use that rap and silicone spray.    

Answer 2

i don't think it will work because unlike the silicone the paint is not flexible and you get chunks of mud beating on it it will chip off.  the silicone is a much more flexible sealer

No, the high temp paint has to dry on a hard surface for about 7 hours to set properly, the header wrap is a porous surface. So, if your worrying about high temps, spray the headers with the paint first then wrap em, but if you know your gonna get it wet then s***w the wrap!
