Painting the wood near the glass panes on your windows is definitely a pain. This trick is so easy, you’ll wonder why you didn’t think of before. Take a cotton swab or small applicator and rub petroleum jelly on the glass next to the wood. Any stray brush marks won’t stick to the glass, so you can easily wipe away your mistakes. This works for painting around doorknobs and hinges, too.
Believe it or not;
To prevent white paint from turning yellow, stir in a drop of black paint.
