Have you had problems with paint sticking to fine brass wire used for
grab irons or handrails?
We have found that if you use a chemical blackening agent as a primer
that the paint sticks better and if it chips bare brass won't show through.
Make sure that you clean the brass wire when you start the process of
bending grab irons or stirrups. This will allow the blackener to work
more effectively. You can use the same process for flat wire as well as
round. Try it on your next project.
