What is the smoothest you could make a wood surface?

I know the conventional methods, but beyond fine sandpaper/steel wool, how can you make a piece of pine smoother than glass?

Scrapping is a time honored manner. Of course some kind of filler before painting is good too.

Do transparent surfaces count (i.e., polyurethanes, etc)?

Some woodworkers use hand scrapers to get an extremely smooth surface.

Very sharp hand plane, and adjusted correctly for a very light cut. Pine is a little tricky with all the resin, but experimenting with high and low angles, I'm sure you could get an outstanding surface.

Electrolyze water and collect the hydrogen and oxygen gas. Burn the wood with just enough oxygen gas to get mostly carbon monoxide.

Highly involved, but effective, and I doubt the rule book specifically excludes this approach.

If you want a smooth board without finishing then you're pretty much stuck with fine grit sanding. However if you want to use finishes then I would recommend applying an oil finish & then finishing it off with layers of woodworking paste wax, each time sand with a fine grit or fine steel wool between coats (you should be removing most of the wax each time). The last coat is buffed to a polish. That is the best method I've come across for a smooth finish. I use Minwax ... but I don't use their basic use instructions.

Uhmmm. Shouldn't this come with a disclaimer "kids, don't try this at home"

Yes, kids, don't try this at home. Adults, you shouldn't try it at home, either. Save it for an appropriate laboratory. As they say in racing, speed costs money.

General shape is ultimately more important to aerodynamics than surface finish.

Yup, deal with form drag and interference drag first, then worry about skin friction.

Many coats and a fine sanding in between is the key to a glass like finish. And after the last coat of paint or polyurethane, use rubbing compound like you use on your car.

Is this for a pine derby?

Urethane that has been polished with a buffing wheel. I'd concentrate on the wheels though. I was a fan of using shaved graphite as a lubricant. I also would sand the inside of the wheels to lower their weight (lowered rotational inertia).

Completely correct. Skin friction is almost nil.

Don't you already know how to polish your wood? Most boys learn it by the time they are out of middle school.

Another trick is to soak the wood in water between sanding... it causes it to swell and contract. Although, I think this applies more to the cutting board I made based on the fact it would be long term use, and get wet often.
