various papers or pads are just fine for most all over and around about any firearm,BUT the top strap or the top of a vent rib, that is "matte finished" as noted above needs to be bead blasted, we always used "used" glass beads we got from the wire department of where we used to work, and always used 'low' pressure ,yes must tape off the sides, to get the proper finish difference of the sides, versus the top strap of a "matte" finish....YES, you can use a 'pad' for the top strap of say a GP100 or Security six and so on.......with practice and time, it works out great 8)
