Powder Coat it.
Bob: I assume that you are on the hard for now. I do not know how much work it is to remove you bowsprit/anchor roller. If it can be taken off of the boat without too much trouble, I would recommend that you have it powder coated. This process involves removal of all of the old paint and then they charge the metal with an electro static charge. They then spray the object with a powder that is then baked on. There is really no comparison to paint and powder coating as far as appearance and durability. If you do this you should also use some silicon or anti-sieze gel on each of the screws/bolts when replacing the piece. This will prevent the powder coating from chipping and allow any salt from getting under the finish. I think that this would cost approx. $50-75 but it is really first class when done. They can do it in any color and different finishes if you like.
