I have to say that years ago I would try to persevere by hand with a fine brush and a load of patience but you really can't beat masking.
There are a number of ways of acheiving the mask though from sellotape, through masking tape to specially purpose manufactured masks. The manufactured ones are good but expensive and not that much better than you can make yourself.
At least with masking you can try again and again to your hearts content until you get it right before committing to paint.
Just bear in mind that sellotape tends to adhere quite strongly and can leave gum behind but it does have a thinner edge. Masking tape is a lot more flexible and can be bought in fine line form which is very flexible and a lot easier to use.
Finally you could use a masking fluid. This works by first masking the frame itself, obviously a lot easier than masking the panes, then paint the area with a masking fluid, purchased from any model shop. You then remove the hard mask and paint the frame. Finally the masking fluid is removed with a sharp blade and a perfect frame is left.
It all depends on the size and complexity of the window you are doing as to what you might feel is the best method. |
