Top photo: After applying the 1201 conversion coating for preservation against oxidation and white rust. The single pulley at left rear is half coated with 1201 which contains a yellow die that isn't very noticeable. The double pulley in front is still wet with the 1201. The preservation should last a few years, at least as long as you can see some yellow die. This is a good reason not to use the Alodine 1001 which has no die.

Bottom photo: Just the right half is coated with 1201. Keep in mind that the lighting is yellow fluorescent.
