WORST Rust on my hatch. What should I do?

[Nintensity]

So I bought a 240sx on Craigslist for 700 bucks. Engine sounds perfect but the body needed to be done. It was definitely rusting in the hatch.

The spoiler was loose and flopping around. I suppose the previous owner put glue to hold it down. So i decided to investigate. RIP to the spoiler.

Omg I never seen anything as terrible as this in my life. I've worked with rust before, but nothing THIS bad. Owner used silicone to plug up the holes but it didn't go well as planned. So i ripped it off. and came to this:

Needless to say, I sanded down most of the rust, but it's still BAD as hell. I don't have plans to put $$$ money into this as i'm planning to sell it.

What do you think is the cheapest and ideal solution? Frickk :(

find an other wing and slap it on.

Find an OEM Hatch that never knew the pleasure of a spoiler. Install. Profit.

I've seen them go for like $100 around here.

definitely get a wingless oem hatch. not worth fixing.
