Sounds to me like a disaster in the making. Pros who spray everything
else still paint windows (don't know about widows) with a brush. There
must be a reason. I think you have two options-- 1) learn to cut in a
clean line with a brush (a skill you will never regret picking up) or 2)
Pay someone who has learned to cut in a clean line with a brush.

If you DIY, with 40 windows you'll have plenty of time to practice.
Start with the least visible ones and work towards the ones you'll see
every day. Masking tape is a pain in the butt-- you don't get a clean
line, with paint seeping at the edges and tearing unevenly when it comes
off, and half the time it pulls paint you wanted to leave off the wall.

Get a really good brush (expect to pay $25-30 for a 2" sash brush) and
lay off the caffeine!

Hi,



Now, I am faced with what seems to be a very large task of actually painting
all of the window frames and jambs. There are a lot of them (40+). The
walls and floors are finished , so I can't make a mess. And, I need the
finished painting to be high quality, i.e., smooth, free of brush or
rollermarks, etc.

It seems to me that my best approach would be to mask off each window and
door - masking a foot or so of the wall around each unit. Then, with the
right spray equipment, I might be able to spray each unit fairly rapidly.
My concern is overspray - I can't mess up the paint on surrounding walls,
floors, or ceilings.
