I just filed my IR leds this morning for larger beam angle. I used a "medium rough" metal file and no sand paper. I had a problem with too bright leds so I didn't do the sand paper grinding. Now the leds have a nice wide angle and they are not too bright anymore :P
Here is a image of a filed down led (not taken by me, found it from another tread here...) which should give you some idea how much to file away...
