It won't hurt to have it on all mating surfaces, but what I do is this:
And yes that's about as far as my photo editing goes ... Just make sure you go with a nice thin uniform layer. My $0.02

All mating surfaces I used three bond bead it and spread it evenly with index and forfinger

IMPORTANT: When beginning the application of
the crankcase sealant, the assembly and the first
torquing should be done within 10 minutes. It is
suggested to have all you need on hand to save
NOTE: It is recommended to apply this specific
sealant as described here to get an uniform application
without lumps. If you do not use the roller
method, you may use your finger to uniformly distribute
Use the silicone-based Loctite 5910 (P/N 293 800
081) on mating surfaces.
CAUTION: Do not use other products to seal
crankcase. Do not use an activator with the
Loctite 5910. Using other products or non silicone-
based sealant over a previously sealed
crankcase with Loctite 5910 will lead to poor
adhesion and possibly a leaking crankcase.
NOTE: Refer to the product label for the sealant
curing time. Respect the manufacturer's recommendations
prior to start engine.
Use a plexiglass plate and apply some sealant on
it. Use a soft rubber roller (50 - 75 mm (2 - 3 in))
(available in arts products suppliers for printmaking)
and roll the sealant to get a thin uniform coat
on the plate (spread as necessary). When ready,
apply the sealant on crankcase mating surfaces.
Do not apply in excess as it will spread out inside
Tighten cylinder block screws as per following procedure:
Apply Loctite 243 (blue) (P/N 293 800 060) on
Torque cylinder block screws no. 3 to 40 N•m
(29 lbf•ft) following sequence 1 to 8 and then to
55 N•m (41 lbf•ft) (repeat sequence).
Torque cylinder block screws no. 7 to 22 N•m
(17 lbf•ft) following sequence 9 to 23.

I use three bond 1211, but don't spread it. I simply put a 1/16" or so bead in the center of all the mating areas, which goes on really quick, and very even as it is easier to judge how much is there. Then just put the case halves together. You know you have the right amount down if it appears around all the edges, but doesn't protude out very much.
I adopted this method after seeing it done with a robot in an engine manufacturing facility.
