Marker lights Galvanic corrosion?

[jeffrey]

I damaged the fender on my 2015 quicksilver and had to remove a marker light.  Was surprised to see so much corrosion on it already.   Looks like two dissimilar metals and galvanic corrosion.  Anyone know how to slow down this process?  Would it be worth my trouble to take off all the covers on my lights and spray them with something like wd-40? Did drive through Colorado and South Dakota a month ago. Might just be from salt on the roads?

That's too bad.

Instead of WD40, consider something like this, used on aluminum airplanes:



 

In a pinch, I've also used motorcycle chain wax, which seems to have similar anti-corrosion properties.

I just looked and several varieties are available on Amazon.

The typical aviation sources are Aircraft Spruce and Wag Aero.

I you have an airport nearby with much general aviation traffic and a pilot shop, they may carry it as well.

Also consider CRC. It's available at almost every auto parts store and hardware centers, it should do the trick..
