Swabbing the upper end of the hole is enough and let the pin drag the fluid 
down with it.  You don't want it running out the bottom.  If you dip the pin 
and are using plate bushings, the stuff will get all over the place.

 The best way I have found is to take a 'spinet' hammer shank ..........CA a 
round punching made from key bushing cloth to the end....be sure to make the 
punching a size that will just fit into the pinblock dry without have to 
really push on it........ dip the hammer shank mit der punching into your 
favorite fluid and swab the hole........just far enough into the fluid to 
barely cover the punching is sufficient (if you are having puddling/dripping 
problems you are using to much fluid) Swab as many holes as you will pin in 
the next several hours cause if you don't you negate the facility of using 
the driving fluid..........be sure and cover the keybed with newspaper to 
catch any wayward drips:) (Don't ask)
 If you are pinning a plate with bushings apply the fluid 'before' you insert 
the bushings...walla ...no mess :-)
 The pins will be snug, but seemingly loose, to the feel for a few days but 
will settle down/increase to a very good tuning torque in a few 
days............
 This procedure works extremely well on a non-rock, a.k.a. 
delignit/falconwood,etc., block...I've never tried it on the rocks:)
 I drill a .250 hole, single pass, using a new drill bit for every block and 
2/0 by 2 3/8 or 1/2 pins....works for me.
