Powder Coat Questions

[Zsled]

Hey I was thinking of powder coating my header and coil over springs. Has anyone done this? Will the headers flake? Will the springs flex cause the powder coat to crack?

[Dave Sommers]

Springs are generally no problem and will hold up, the header on the other hand will not. Powder coating is a resin product that is electrostaticly deposited on the metal and then heat cured at around 450. Headers get way too hot and the resin melts off.

If you want to try something for headers, the Jet Hot product works well most of the time but make sure you get their high temp version or it will also not hold up over time. Getting a set of Z headers Jet Hotted is around 175 or so, maybe more as mine were done some time ago.

Hi Zsled,

As for your headers, there is a product made by the POR 15 people called Black Velvet. It is made specifically for exhaust manifolds and is claimed to withstand temperatures up to 1200 degrees F.

I personally haven't used this stuff, but from what I've heard about POR 15 in forums at this web site, it should perform as advertised. And it can be brushed on or thinned and sprayed on.

At a cost of $26.00 USD I would think it would be worth looking into.
