I just did a tru-oil neck (maple) and it came out great. However, my technique was different than what is suggested above. First, I put down some heavy coats (two). I allowed each to dry 12 hours, just to be sure. I then used a 000 micro pad to take all the sheen off. Basically, I got after it a bit. After that I applied a smooth coat every four hours, but with each of these coats just as soon as I wiped them on I wiped them back off with a soft lint-free cotton cloth. Each coat came out very, very glossy and very, very smooth. When I had an issue with anything irregular in the finish I would simply take the 000 to the neck, tack off the dust, and apply more thin coats. I think I ended up with about 16, but could have easily stopped much earlier.
The key is to make the coats thin - wipe on, rub in with the fingers, and wipe off gently.
The neck is now "curing" and although BC says you only have to wait about 48-72 hours I am letting it sit a week. After that I may just apply some lemon oil and be done, or may knock the gloss down to a satin.
Bottom line - the neck is very smooth and well protected. And you can do it all on your kitchen counter (wife permitting...).
