Topic: 68-Up Backfire Valve Restoration, Treating the Aluminum

[Craners]

I?m almost to the point of needing to apply a protective coating on the aluminum.

Looking for recommendations for preserving the exterior of the aluminum/surface finish.
I was thinking about using a clear chem film type product.

Has anyone found a good product to preserve the aluminum ?

Thank you

Don't know what is currently available but in the past when I needed a similar product I looked to the big rigs. They often have a lot of aluminum work on their rigs and always seem to have a ton of products for protecting those surfaces. Some others might suggest military, for polished surfaces on ships though there are allot of hands available to keep those shinny or air craft

Sorry don't have a particular current favorite. Maybe someone else will

You might also consider a good wax or ceramic coat to protect these though I never had a problem with the surfaces on those valves considering how the cars are currently maintained and stored

On some Magnesium wheels once polished would start to tarnish after 3 days. I used T9 or Boeshield (a oil based metal preservative) on them which would preserve them for four or five months . I imagine on aluminum it would be far longer. Eastwood sells products for your purpose .  https://www.eastwood.com/eastwood-diamond-clear-gloss-aerosol-11oz.html
