All Pro bumper paint falling off and rusty

So I bought this bumper from another Tacoma owner and noticed some rust points. So I took the bumper apart and started scraping and sanding the paint off. I found there was way more rust under the paint. Has anyone ever heard or seen this happen? I was excited to get it and now disappointed at the quality. The bumper has only been in the Colorado Springs area.
These are pictures of just the center piece. I have already sanded and painted the other parts. It is taking me a while since work takes up most of my time.

 

It's a plate steel bumper... media blast it and prime it and paint it... unless that rust is THROUGH the plate (not likely) it should be expected. - I don't beleive all pro sends their bumpers painted so you can put that on the previous owner, but it shoudl hvae been disclosed IMHO

 

par for the course with that all pro bumper. they had some shitty powder coating done. best bet is to do like zmw said and get it blasted and re painted

 

I'm trying it myself. I grinded the rust off and used hammer lite paint. Used it on my rock crawler and its great. So I will take pics and update as this bumper progresses.

 

I ended up havin mine welded together after it was sand blasted then painted it
