Advice on detail follow-up

[GoCubsGo]

I'm looking for some advice on following up my first paint corrrection. My first correction didn't fully correct 2 deep scratches (one on the hood and the other on the roof) and I have since been hit with 2 bird dropping etchings (one on a different area of the hood and the other on a different area of the roof).



I plan on re-hitting the scratches and etchings with Menzerna SIP(PO83Q) and a LC orange pad with a PC 7424. If that doesn't work I'll move up to M105 with a LC orange, and if that doesn't work move to M105 with a LC purple (I'll be careful, I've done enough research and watched enough online videos on M105 to make my head spin).



I'm not worried about the correction or follow-up sealants/waxes, I need advice on "blending" the newly corrected areas with the rest of the panel.



Should I plan on hitting the entire panel with my finishing polish?



Any advice on proper technique or tips for blending the SIP or M105 from a specific area of a panel with the rest of the panel with a finishing polish?



I searched, but didn't find anything that answered my questions.



Auto in question: 2005 BMW M3 (Carbon Black)



Thx

Maybe these scratches are too deep and can't be corrected without risking removing too much clear coat and causing clear coat failure. Might not even be able to correct them with a PC anyway, you might need a rotary to remove deep scratches, but I would just live with them and fill them every once in a while.

I was very passive with my first detail. I stopped by an experienced Autopian's shop after my correction and he advised me that a more focused SIP or M105 application with a PC should be enough to take care of the scratches. Looking for some blending techniques or tips. Thx again.
