There is probably an easy explanation but here comes a question about steel and aluminum. In another thread about "dressing the Scotchbrite wheel" the question abut fine slivers of steel getting mixed with the aluminum would cause corrosion. If this is true..... The HS and VS hinge brackets are match drilled to the spars. These are powder coated but after the hinge brackets are drilled, any powder coating is gone from inside the holes. Then when they are riveted in place there is an aluminum rivet making contact inside the steel bracket. Why doesn't this become a corrosion prblem? Is it because the contact point is sealed from the evironment?
