Replying to Rusty edges

A friend of mine just bought a pair of the old 177cm cusson 1080s for dirt cheap. however 4 weeks later he notices minor rusting on the edges of the skis, now these haven't been skied or drilled yet.

Does the rust affect performance or life of the ski ? can it be fixed? he doesnt really want to return it because he got it for so cheep
