Swinging arm before and after painting

Pictures of the rear swinging arm before and after stripping and painting.
I stripped it with paint stripper rather than getting it shot blast, as I could leave all the shaft drive internals in place. The swinging arm is steel and the hub aluminium so all was stripped and cleaned with all sorts of abrasives to get it all back to bare metal. The arm was then sprayed with zinc galanising spray and then finished with a metalic silver colour similar to the original.
I am trying to get the bike to look ok but more importantly to be corrosion resistant.
I use a bike most days all year round for work so with living in Cornwall not far from the sea and our mild/damp winters rust is always a big enemy.
