M105 to remove sanding marks via whichever pad you wish. M105 is very different & more aggressive than PlastX (although may not be as aggressive if you are using 3M Compounds). M205 to remove any marks from compounding & to further refine clarity. So this would be our recommendation for you. These products are actually sold in small 8 oz sizes through some outlets if you did want to try them out.
Another thought, keep in mind that the quality of your sanding/finishing abrasives will play a large roll in how even & deep of sanding marks you are inflicting, in turn how easy removal is. In other words not all automotive sandpaper technology is the same. We specifically would recommend at least further refining with a foam back finishing disc by machine. We recommend our Meguiar's Unigrit or 3M Trizact. Additionally, refining more, especially with a foam backed disc, up to 3000 grit, will make sanding mark removal much less invasive.
