Rusty,
I snapped some pics last night to update my handi pics and took a couple of the bedliner spray I was talking about.
Here is a shot of the complete gun.
Here is a shot of FACTORY synthetic butt.
Now here is a WOOD for-end, I sanded and sprayed with Duplicolor Truck bed liner spray.
Finally here is one of both Butt and For-end stocks in the same shot.
Its VERY easy and IMHO looks great.
for JUST a dull finish you could simply steel wool the stock to the sheen you desire. If a more durable, Matt finish is desired about any spray clear finish in dull/Matt should work fine. Staples or any good office/art supply will have these. Artists use them to "MATT" these work. Especially pastels....
