Do you replace or reuse rusty hardware?

[In The Ten Ring]

By the time my truck is reassembled, I would have cleaned up so many nuts, bolts, washers, and screws, it'll get 30 mpg!

I studiously clean up and plan to reuse every single fastener I can off my truck. Do you do that too or just get new ones?

Do you reassemble without cleaning up the bolts, etc?
