Your going to have to take some time to sand and repaint I'd say. But this can be a great opportunity to make sure the accent color of your outside window frames suits your house, and it will definatly make your home much better looking whether you change the color or not. You'll need a good quality outdoor paint, you need to cover ALL your glass neatly, sand, do small repairs, maybe prime then paint.----------------------------I don't have any step by step solutions, but I've got to do the same thing and I know it's NOT a two hour project. You need to think, how long will it take/cost per window, and plan from there. Get or rent a decent sander specifically suited to this project, you'll save time and sweat.--------------------------I'd post some links but I know know if that is allowed here at this time. Go take advantage of those people working at your helpful hardware store.------------------------heck, even if you can only do one window at a time, one per month or whatever, do it, you'll love the look and that wood should be protected!
