I blame myself!! Now, while the persons tinting the windows on
China today did the actual damage, I simply should have prepared for this. I offer this post for yall to think about prior to having things done to your car.
China's interior is in pretty good shape. The back seat was really clean with no tears and most importantly, NO SPLIT SEAMS!! Now, I knew the padding in the upper back seat was getting crunchy, and I knew the window tinting dudes would be back there, but I didn't know what a dick-hammering it all would take. Sadly, in hindsight, I should have removed the rear seat, upper and lower prior to taking it for tinting. Tough lesson......

Here is what I was left with after tinting.
Notice the wrinkles in the seat back, and the now non-straight line the top of the seat back is in:
Also, there wasn't a split seam to be found anywhere. Now:
Also, you can't really tell from this pic as I had it tucked in briefly, but they broke off the forward most tip of the inner C-pillar cover. The fabric doesn't stay on, and also it doesn't stay flat against the side of the car.
And I'm guessing this will clean off, but tint guys just firehose the inside of the car to lube up the glass, and the medical kit cover was perfectly clean and even-colored before today.
I called the owner and let him know what happened, that I wasn't pleased, and that they should be more careful before ruining the next old car. He was a bit defensive and mentioned the reason I was having the windows tinted was the years of baking the car interior, especially the rear shelf and seat. He also was not an A-hole in any way. He is also an '85 mile round trip away.
So, like I said, I mostly blame myself. I could have prevented this. I'm not gonna waste time blaming others.
Actually, they did a great job tinting the windows, and I would actually use them again if needed. But I would take steps to prepare "for the worst".....
In the meantime I will keep my eyes open for a rear seat back in I think it's called
Sand Pebble, or some-such....
