I am sanding my leafspring 289fia from the filed finish to a brushed finsih. 3M makes really nice foam sanding pads that are sold by the box by auto supply companies. The pads work really good in the door jams - they cushion again finger marks/grooves. They come in three grades which approximate 150, 300 and 420 and can be used for wet or dry sanding. They work great in the jams, by the hoodscoop on my car (since it is welded on) and the curved edge around the cockpit. Once you get past 420, you could probably use staight paper since the amount of material you will be removing will be minimal at that point so you won't have to worry as much about finger marks etc.
I find that sanding is a great mindless activity after a long stressful week at work
