Corrosion of capscrews.

05-04-2011, 10:03 AM
I am a new Concours 14 owner. I just noticed that there is a build up of a white powder on certain capscrews around the rear wheel/brake area.
Are these capscrews aluminum? Is there a way of preventing what appears to be corrosion?

It's galvanic corrosion. I use Corrosion X, but if it's a torqued part the torque must be reduced. Nickel anti-seize will work too.
