Painting turns out to be somewhat expensive depending where you live. This is not a problem when you have a large budget for this kind of jobs. However, this is something that can be done by yourself and it saves you lots of money.
Here are some tips:

- Cover ALL windows with plastic, no matter if you're using a brush or a spraying machine. At least cover the edges with special Painting Tape.

- If you use masking tape on your window edge don't leave it there too long because it wont come off easily after the sun hits it directly. The glue melts and then you'll have to use cooking oil to get it off.

- Start from top to bottom, this way if you spill you can fix it later...
