I only use the hand tools for doing internal commercial work and I find that we spend a lot of time wringing them out before use so not to get water everywhere.
Al,
I do a fair bit of internal work.
It's easy.
Dip your applicator into the bucket and run your squeegy down the applicator (while holding it above the bucket to catch the drips) to remove the excess water.
Then when squeegying windows, after you've washed, hold your applicator under your squeegy and squeegy as normal. The drips will run down onto your applicator.
The last couple of inches of window won't make much difference; just squeegie and scrim any drips.
