Sanding out orange peel in clear what grit to use first?

I did on my dart last month 1500 then 2000 then 3000 to get the overspray off the car and hand polished it with Rubbing Compound followed up by Polishing compound

Took a week because I did the car in Rubbing Compound right after finished sanding to reseal the paint then did the car in sections with Polishing Compound only spending a couple hours a day on it and 2 Microfiber Cloths for each Compound

The paint looks a thousand times better
I wanna redo the polishing again to get it even nicer but i did it the way I knew how to and am learnig to use an electric buffer at the moment
