Hondabond i got is super tacky and no chance to do it with brush, think next time I will use plain sharp plastic edge, I used cardboard this time.
Just realised that I haven't scored or glued crews on starting clutch, so will split casings again... not to keen but better now since all I have to do is take clutch and gear shift mechanism off.
Getting there slowly...
I always used a modellers paint brush to apply the crankcase sealant. In my day it was always Hylomar but the new Honda stuff is great as well.
