What this will do is add pressure to the system (2-3 lbs) which will help force the sealer into the seeping area. Once you have run the engine for awhile (we typically run them for about an hour on our run-in stand after retorquing the head gasket). At that point, drain the coolant with sealer and then thoroughly flush the Radiator separately to get any remaining sealer out of the tubes so it won't plug the tubes. Then let the block sealer dry overnight, and you will be good. I'm sure there are other ways too, but this has worked well for us.

I think that's a good idea, pushing the sealer into the minute cracks.
