Aerosport rear seat fixup

I cut the pins to attach the rear seats:

I sent the seat backs to Aerosport to have them covered, and later received them back - they look great!

An issue I found is that apparently they riveted a metal backing to the rear seats, without removing the plastic from the metal or deburring the metal - so I removed the rivets to clean it up:

Once I removed the upholstery that covers that part and removed the rivets, a few different issues became apparent - not only did they leave plastic under the rivets and the full back side, but also the holes were not deburred, some rivets were set at an angle, they hit the seat back aluminum angles with the drill bit on every hole they drilled on the corrugation (this one is not a big deal, I admit, but them not being careful with my work was a bit upsetting), and some holes were below the minimum edge distance.

All of this was true for both seats, so I can't believe it was an oversight. I reached out to Geoff from Aerosport with this feedback, so I'm confident it'll be addressed if it hasn't been already.

After fixing all of that and rounding the corners, I applied some primer and riveted the backing plates back on:

Last but not least, while reassembling the seats I noticed one of the velcros on one of the seats was swapped (the same side was on both mating parts, which prevents attaching that bit (not a big deal, there's many other velcros around it that will secure the upholstery just fine):

With this fixed, the only left for the rear seats is final-attaching them in place.

Time lapse:

Total rear seat rivets: 124
Total rear seat time: 17.9h
