Rusty colored coolant

Today I was going to change my coolant and upon draining the radiator, noticed a rusty colored coolant coming out of it. it drained pretty good. After flushing the radiator with water to flush it until clear water came out, I noticed that the radiator inside is kind of rusty. My question is, is my radiator done and need to be replaced?. It's not leaking but I'm not sure if there is an impending problem coming.

I had the same stuff in mine. I already had a replacement radiator so I swapped it out. No need to change it out unless it's leaking.

The rusty stuff is what came in the Jeep from the factory. I just replaced it with the green stuff that says " suitable for all vehicles regardless of color of antifreeze" I used Peak i think.
