Rust on lower fork bracket

[Deanohh_imp]

Any protection used under the fenders will have a very difficult job. That's a spot that is constantly being washed and abraded by road chemicals, sand, pebbles, and water thrown up pretty forcefully by the tires. Without additional protection, even a thick chrome plating will eventually be worn through to bare steel by the tire wash.

Something under there is probably better than nothing but if its painted or under coated, it will be difficult to get good adhesion to the chrome plating. If some paint ever chips off a little, that spot will become a trap for corrosion to start and eat under the rest of the paint or coating.

Makes me think about attaching some sacrificial zinc anodes like they use on boats.
