Too Rough To Save?

Maybe you could make a race car out of it. They used to go through a lot of effort to acid dip them to lighten them up. Yours let mother nature do it and it's got to be a lot lighter now.

Seriously, if you don't count your labor and can do it all yourself, treat it as a challenge. I don't weld so any work like yours I would have to pay for, so I would probably cut and run. But consider the bragging rights you'd have when you show the before/after photos.
