That whole "sanding in" process sounds interesting. Also seems like a hell of a lota work.
Takes time.
As mentioned I didn't do the 600, but I did the 400 twice. You can get 600 from an automotive painting supply store if you want that level of finish. Other than that I pretty much followed the directions on that web page. After the final sanding and final wiping with a cotton cloth (instead of the paper roll on the last sanding) I let it dry for over 48 hours. Then added a couple coats of floor wax. Used a stain with some polyurethane in it - remember its first mixed and thinned out like water with the Mineral Spirits. Suggest getting the odorless Mineral Spirits.
I did a few days of degreasing (rubbing alcohol) and dry sanding first with 220 because this furniture was really old and had lots of oils and varnish on them. I wanted them clean enough to except the stain but I did
not want to strip them to bare wood.
During the first 3-4 wet standings with 220 it looks like shiza, but then gets better and better when your into the 320 sanding rounds. I rigged a drying cabinet from a cardboard box and hung the grip and stock inside from wires during the tacky stages and for each overnight drying. The hand guards can just set off to the sides on the bottom of the box. I don't have any pics of any of that stuff. Sorry.


JB Weld Metal Epoxy coat on back of upper handguard - (de-greased, cleaned it up, and roughed up surface first)
I heard it crack on installation but at least did not break in totally in half. 
Final wipe with cloth.


Forget about the color for a minute if you don't like it, but pics really don't do the finish justice. The distressed marks and discoloration of the original 50 year old wood is still there and that's what I was aiming for. Worth the time, effort and cramped fingers? I think it was for one of my VZ2000 rifles. Will I still be able to play the piano? Never could before.
Some day I will actually get around to putting it on the gun. But that would mean actually
finishing a project and I don't want to ruin my reputation. DOH!
