I had a vintage Falcon donated to me in super bad shape. Missing everything and broken in several places. I figured it had seen some action in its day. I imagined it sitting outside of Han Solo's retirement pad with a sign in the window (For Sale: Needs Hyperdrive)

Behold. The abandoned Millennium Falcon. Purists will curse me, I know.

I weathered it using Tamiya Weathering dry brush paints. I then use liquefied iron filings and a rust activating solution to make real rust grow on the plastic. As time goes on it will get more rusty.

I fabbed the propulsion components from a 1970s half built Sealab3 model.
