STEP FOUR: POLYMERIZATION.
This is where the magic happens. Put a (hopefully) clean sock on your hand like a glove. Your going to use it to rub oil on the neck.
Your neck should have a nice satiny glow at this point. It wont absorb oil AS fast, but its still thirsty, I promise.
Sit your fret board on carpet fretboard down of course.
-With your sock, put a SMALL amount of oil on your finger.
-Apply the oil in a smallish spot.
-Rub HARD. You want it to get HOT. Be careful, as you rub you CAN/WILL get it hot enough to burn yourself. Use common sense here.
- As you rub, you will notice it start to get REALLY shiny. Make sure you work evenly and across the neck. You cant mess this part up, but you can miss spots, so watch for that. Just run the neck under the light to see any spots you missed.
After you''re done with the sock, you're going to apply a dime size amount of oil and rub it on your hand. Youre going to repeat the process rubbing down the neck with your bare hand. It gets MUCH hotter much faster, so again, be careful. You will reflex away before you get burnt, but it doesnt make it hurt any less
Youre going to do this about 3-5 times. It will be extremely shiny when you're done. It will also be dry to the touch. DO NOT HANDLE IT! Let it sit for about an hour.
Come back... it will be satin again. Do this process one more time.
Between these "sessions" apply more thin coats of oil to the fret board.
By doing this process you also eliminate any "raised grain" problems people have with simple apply-and-dry method.
After you do this 2 or 3 times (depending on how bad your neck is!), it will look like this. *NOTE!* It will "feel" dry, but do not handle your neck at this point. You need to let it sit over night to harden.
