he was not afk or anything

This is a photo after 48 hours of applying clear coat. I used 800 1000 1500 2500 sandpaper. Any idea why there are these scratches?

I bought a aftermarket radio my my z3 but when i wanted to remove the old one, I found that it was stuck. The screws are totally destroyed and the spin in place. As you can see the radio is not sitting flush and it can slightly wiggle but it is completely stuck. what should I do?

is it possible to take out just this part of the center console on the bmw z3?

I have a BMW Z3 1.8 (M43, 118hp, cable throttle) and today I cleaned the throttle body because the car had slightly rough throttle response at low RPM.
After cleaning, I started getting a weird issue:
the throttle pedal physically sticks right at initial input
especially in 2nd and 3rd gear at low RPM
if I press a bit harder, it suddenly “pops” free and then becomes smooth again
in neutral and with engine off, it feels mostly normal/smoother
I removed the intake and inspected the throttle body more closely and I noticed what looks like a crack inside the bore near the butterfly flap.
The butterfly flap also seems to slightly rub/contact the bore at the fully closed position, which is why I’m wondering if the housing might actually be damaged or warped.
I attached a video of the inside of the throttle body.
My question is:
is this actually cracked/damaged?
or is it maybe just a casting mark or normal wear?
could this realistically cause the sticking throttle symptom?
The throttle body is mechanical/cable operated, not drive-by-wire.
Thanks for any help — I don’t want to replace the throttle body if this is actually normal.
