1990 toyota 4runner rust issues

[arispero]

So recently my friend gave me a 1990 toyotoyota 4runner and the passenger rear fender right below the gas tank has about thred inches of extreme rust. What's the best way to fix that? Is there a place I can buy a new rear fender? Or some other way to fix it? We welded on a pipiece of metal but it looks terrible and I want to find a way to fix it.

There are some aftermarket fiberglass panels available.
Depending on how bad your current fix is, some bondp on top of it might help.
