2022 Toyota Tacoma Off-Road Rear Bumpers

I purchased my first bumper to replace my factory one after it was damaged in an accident. After a few months, I noticed the welds started to rust on the surface. A replacement was ordered and the first one was returned. Just tightening screws on the new one chipped the powder coating which started to rust. I contacted Westin again and they sent me a can of touch up paint. Now the entire edge on the top of the bumper under the tailgate is starting to chip and rust. The bumper isn’t even a year old and I’m expected to keep touching it up!!
