It's all about trusting your technique and cutting corners.
I spend far less time edging(or detailing if you like) these days.
I know that with one or two quick swipes it'll dry without smearing.
I'm quick with a squeegee yes, but I do miss the edges at times, and it's quicker to pick up runs after than squeegee really slowly and deliberately.
I only wash up to half-inch from the edges too.
You'll do the edges with the squeegee and shine up with your scrim after.
Washing to the edges will give you far more excess water down the sides to mop up.
If it's really greasy then wash right over the edges and run round with your wet scrim first.
Then it's just a case of a normal squeegee job, and hardly any edging to do.
If small opening lights are pretty clean, then a quick mist with window spray and squeegee off, again hardly any excess water.
It's all about learning to keep mopping up to a minimum for me.
I'm still getting faster now after 8 years!
Hope this helps in some way.
Cheers, Rog.
