Subframe advice??

[Jono FD3]

Guys, my FD is starting to show surface rust on the rear subframe...... Now I\'m planning on dropping it our to clean it up and waxoil the floor pan under it while everything is out, but the thing is, I\'ve thought about getting the subframe galvanised, and then painting it red...... what are your thoughts on the galvanising front??? never have any rot issues with it again!
