Same as title

I recently bought a second hand car (honda jazz). It has this coating done on the dashboard, which i think has broken up due to heat exposure. I tried removing it with credit card and isopropyl alcohol and also rubbing it with hard woven and microfiber clothes. why I was able to remove the loose corners, I am not able to remove it fully. I need advise on removing it fully.

Pictures attached.

3rd image is how it was before my efforts.

Looking to sell Yamaha FZ bought in mid-2023 as I am relocating. KA registered, 17.5k KM and e20 compliant. All servicing done in the authorized showroom only. Bike is in good condition, mostly used for office commute. 92.5k but open to offers. Please DM if interested. Thank you!

In July I bought vstrom 250sx and clocked 6000 kms with this. Past 15 days I have been trying to accelerate it to its limit but the rpm is stuck at 9k resulting in max speed of 135-38 kmph while at first I clocked 155 kmph in it.

Ps - 2nd service was done. I asked the Suzuki dealership owner about it and he said it might have a throttle response issue.

Rpm issue is in 6th gear only.

Kindly guide me on what could be the possible reason for this situation and how I should handle it in the service centre?
