I've been using one of these magnetic base antennas that have a rubber cover on my trunk. Recently I did a wash which I always remove it prior, but noticed this dark, brownish residue it left. I've tried different things like polish, clay and even gently with isopropyl alcohol, but nothing has worked. Couple of questions-

Could this have been some sort of chemical reaction from the rubber cover?

Being that nothing I've tried has worked, is this embedded under the clear coat?

Is there anything else I can try that doesn't have to repaint?

Has anyone else had this happen on their mini 7? More often than not, when I'm in portrait mode and using split keyboard, the spacebar goes missing on the right-hand side (see photo 1). The only way I've found to "fix" it is by either merging the keyboard together and then back to split or by rotating to landscape briefly and then back to portrait. I've tried hard restarting but that hasn't done anything. I have the Mini 7 running IOS 26.4.2.
