I have just purchased a 2004 Bambi and seek advice about how to deal with erosion spots at the seams, external light fixtures, and door hinges. Can these spots be removed? If not how do you keep this problem from spreading?
Lest you get too overwhelmed too quickly, you should know that many relatively new Airstreams have corrosion in the spots that you describe. The Corrosion thread referenced above explains a number of attacks that owners have mounted to get rid of it, or at least to stop the spread.
We wash our trailer frequently, have started spraying the filiform areas with Corrosion-X, and wax at least once per year. The small areas affected around our beltline and rivets have not grown in the last 3 years...and I keep my fingers crossed.

I have roughly the same answer as BDandTT's. I think that my filiform problem hasn't changed in the last year or so. I think besides using the Corrison-X and BoeshieldT9, just by waxing it more---especially along the belt line has stopped the corrision. Good Luck (BTW all I use is Turtle wax soft paste wax).
