Fixing botched paint job?

So the 600 is really working well to smooth it out and overall I think I'm in better shape than I thought. I do have some sand through on edges and a couple thing spots but I think if I hit the thin spots with primer, a touch up gun, resand, and apply 2-3 more coats I should be good. I really need a bigger compressor, so I will probably rent one or buy one if the funds allow. I still want to clear coat it, and this paint is compatible with clear coat. The only reason I went single stage is I thought it would be easier and cheaper. First picture is before sanding and that's not even a bad spot, second is after 600 da.IMG_20240815_130958978_HDR.jpgIMG_20240815_130917744_HDR.jpg
