Technology / Should an exhaust pipe be painted black or silver to best radiate heat?
« on: 14/09/2012 13:57:01 »
Hi,
Not your usual question on here, but I'm a keen reader of these forums, and it's a question I'm not convinced your average mechanic would know the answer to.
I need to replace my entire exhaust system, as my current one has corroded badly. As they're hard to obtain for my car, I want to completely protect the new one from moisture with paint.
My question is, should I use black or silver paint?
I know that black absorbs heat/light radiation, whereas silver reflects it, but what about when the object itself is radiating the heat? Ideally, it wouldn't affect the exhausts heat radiation properties at all, but I can choose from black and silver, would black paint cause the pipes to radiate more heat, or to hold it in?
Any advice would be much appreciated.
Thanks.
