My 1975 Bob Jackson developed rust veins on the fork crown 10 years ago and
the rust has broken the surface at the corner of the crown top recently.
Is there a rust passivator I can apply to arrest this? If I get no better a
dvice I will apply WD-40 in hopes it will seep in and slow the developement
. Eventually maybe I will need to have the crown repainted. The bike looks
new otherwise after 30 years. Brian in Berkeley
