Header Coatings What? Who? How much?
 

The 3.2 for the 914 is nearing completion!

I hate to put the rusty Bursch headers on the shiny new(er) engine.

What are the options for coatings? Pros? Cons? Who in the Seattle area? How much?

Is high heat paint a waste of time?

Thanks

Eddie

Yes High Heat Paint is a waste of time; with the heat cycles the paint won't hold up very long.

Eddie,


Use VHT Flameproof coating. It comes in a rattle can like spraypaint. It requires pretty detailed surface prep (details on website), and after it's applied it needs to be oven cured if the part won't see enough heat to cure it in situ. This stuff is so tough one of the recommended uses is preventing chrome headers from bluing by spraying it INSIDE the pipes as a thermal barrier.

I'vce always used JETHOT coating on my other cars headers. It lowers under hood temps significantly too. not cheap!

I think that is a rumor started by JetHot. I'd like to see some independant data on the temp lowering.

If you can't oven-cure the spray-paint, it's not worth doing. It will only look good for a very short time. Ceramic coating would be your best option if it's available in your area.

Here's another current thread on the same subject.

shbop is right about the oven curing with VHT. If the prep and curing cannot be performed properly, it's best to chose another option. Most v8 shorty headers will cure in place if they are driven hard before being exposed to rain and the like, but I don't know about 911 headers. I'd oven bake the VHT to be sure. It holds up well it you do it right.

Jet hot is very nice, we have used it for years on other hotrods, (before I became a cerified porsche junky). It will keep its original apearance for a long time, we had used a set of headers on a snow plow truck for a customer,a and two seasons later, we could not believe how well the stuff was holding up.
