Will RPM work on aluminum? I am looking for a way to preserve my Edelbrock Aluminum Heads, fabricated valve covers and intake manifold without painting.
Thanks

Hi Scott,

RPM will work on aluminum -Steve,part of Project Valiant) has used RPM on the Aluminum / Magnesium wheels on his truck with good success. We haven't tested it in a high heat situation like exhaust manifold, heads, etc. We did use it on the head pipe of the Valiant and so far it looks like the day it was installed on the car. The Valiant has been through heat cycles and hot enough to see tempature building on the heat gage when we went through the awards ceremony at the Mopar Nats. You can see the head pipe in the post higher in the page. That picture is a recent one after heat cycles. Has anyone else used RPM in a higher prolonged heat situation?
