If you start with a good set of grips it is pretty hassle free. I have about 7 sets of grips and they are all pretty much new but varied between very glossy to very fiber heavy on the surface.
I use the $7 a bag glass bead media from tractor supply and it seems to be perfect for gun work. I've blasted my HK USP 40 slide 3 times now and you can still read the laser etching through the duracoat.
I plan to start selling the grips on Ebay, I figure the factory grips are ugly and the wood grips are expensive so I can hit that market in the middle.
I own firearms not to fight against my government, but to ensure I will not have to.
