Tech related,Need advice on welding rust holes in bumpers

OK,lets say you have a chrome bumper and the sands of time have been unkind and a few holes rust in them.Can they be repaired?or would it be best to just try and find another one?

 

It's just steel right?
If the bumper is for something special,like a Tucker,
your going to repair the original,or make a new one from scratch.

Any mass produced car or truck,see if you can find another one
in better condition.

 

If it's replaceable, replace it.
Just to chrome a bumper is $400 and up.
If it's rare either cut out the rot and re weld it or if holes are small sand blast and braize or solder them.
Ask a plating shop to do repair and it'll cost a fortune, as every hour is on the clock.
