When building a engine and lubricating the crank journals and cylinder walls to hand turn the crank to make sure piston to valve clearance is okay
etc.
My question is. When the engine is fully built how long does it take for the lube to dry out. Can it be sat there for a couple of months?
The stuff I've used in the past says it dissolves in the oil, I don't think they will dry out
which lube do you use :p
Vasaline is good and dissolves quickly in the oil once you get it running.
Whats wrong with good old oil and fill oil galleries though the pressure switch hole and down the oil feed on top of the block. cover cams with oil. On First turn over with plugs out till oil light goes out, job done

I used this stuff: (mostly just because it was easy to add it onto an order for engine bits...)

the engine has now been sitting for far too long (quite a few years 
) but the lube looks the same as it did on day 1
it does drip off a little bit where it was put on a bit thick - but still left a decent coating over all the important bits 
(I just throw a bit
more over it every few months before turning it over to make sure its still free)

The old timer fitters that I worked within the heavy equipment used neat STP or Wynns.
I've seen a race v8 do 20 laps of 1/2mile track with no oil pressure, broken pump drive, and only the high STP content of the oil saved it. When
stripped down the next day, there was no damage to bores or pistons or bearings. I've sworn by the stuff ever since.

Graphogen , made for the job and doesn't drain away, now available in small sachets , my present tube has lasted for several engine rebuilds
I used graphogen - filthy stuff, but it does the job!
