> If you look at Wal-Mart in the section where the Bondo and auto touch-up paint are,you should be able to find 1000 and 2000 grit 3M paper.
As mentioned earlier,auto parts stores like Advance,Autozone,etc usually have a selection. My suggestion is do NOT stop searching until you find sandpaper in as many steps as you can find. 3M has a sampler pack that has 220,320,400 and 600 in it that are available in a LOT of places. I'd also search for 800,1200 and 1500.
Whether you are polishing wood or metal,the whole polishing process is simply about hiding scratches with smaller scratches. The fewer large jumps you have in the process,the better the end result.
A GOOD,silicone-free carnauba paste wax like Meguiar's,or Mother's California Gold is almost a must as a final step after some kind of sealer,which makes it easier next time. If you're not sure on the waxes,if you open the can and the product is a bright/deep yellow and smells like bananas,you're good. Avoid pink/blue products.
Also,I find it quite useful to wipe the wood down with a tiny bit of a liquid cleaner on a paper towel every so often,like denatured alcohol or even plain water as long as you don't use much. This removes all the sanding dust,which attracts more gunk. You can also fool yourself into missing a little bump,sticky spot,etc with all the sanding dust present.
You'll save a lot of elbow grease and time if you have a way to spin the shaft. Tommy D.
