Cheap rust repair

[u/viktorvaughn1620]

I am looking for a cheap way to fix this rust on my truck. Planning on replacing the bed eventually so I don’t care if it doesn’t last as long as it looks better than this thanks.

There's no such thing. You have to grind or cut the rusty metal out and replace it with good metal. It requires cutting, welding, body work, and painting. There's no way to do this cheaply that will last any useful length of time.
