The bed liner paint lasts pretty well...may still get a chip or two where it didn't sitck to the wood unless it was down to bare wood, but it's long wearing stuff with a non-slip texture.
Whatever the wood, it's (1) light colored (2)soft (3) finished in some kind of "lay on the top" finish that chips off and (3) from looking at the wood's grain under the butt plate, seems to be made from small diameter trees. If you get lucky, won't have some bit imperfection that was filled or a knot hole under the finish...won't be sure until after it's stripped.
Jumped on a match stock befor buggering it up with dents/dings, but didn't paint the whole thing. After shooting it a little bit, decided a couple of edges in the grip/trigger finger area had to go....a bit of rasping and some sanding got it to fit right, but the grip area had a sever case of measles.
So masked off the grip area, striped and sanded the area inside the tape, then painted only that area. Makes a nice grip area and isn't unattractive...is a lot easier than strippling.
Painted the insides of the vents on the fore end just to add a bit of the same black color and make the color balance.
So far, with a good bit of shooting, it's lasted very well.
