I've got some metal work to do on my hood, not enough to warrant separation of the skin and braces ( I hope). If I don't split the hood open there will for sure be some surface rust left inside the braces and on the bottom side of the skin where it is covered by braces. I'm wondering what would be the best method to stabilize the rust that will remain in those cavities?

Would it be wiser to apply this treatment before exterior paint, or after paint? I want to make sure I don't do anything to contaminate any surface before I paint it. I realize nothing should be getting through to the exterior surface ... but you know how things have a habit of migrating to the worse possible places.

Thanks
