Mine are the same way and it drives me nuts. I’ve been wanting to clean them up and paint them for months. When I do my seat heaters, I think I will.I think I'm nuts...
These are my seat bases. Before I put them back together (from foam replacement) I wanted to clean them up. The factory did not put any coating on the seat frames or bases. So...even though they are inside the vehicle and my interior is in really good shape, they are rusty. Just surface rust, no pitting, but fer cryin out loud...Its a Jeep, its gonna get wet. Why there is anything unfinished is beyond me.

No one will ever see these...but I'm spending an inordinate amount of time making these pretty.
