If you are going to go thru the effort , folks have had bosses brazed on for V brakes..

then if not the Ti extremities ,you get the powder-coat, or cleat lacquer redone..
or if shiny is all you seek .. put in the labor to polish thru the anodizing layer on the regular brakes

they will water spot, corrode a bit, and need Re polishing , again and again..
the reason the anodizing is done , is to bypass a lot of maintenance of a polished finish..
