How do I remove paint build up?
Answers:    There's auto tint, there's shutters; try shutters if you can afford them. Being in America, I dunno what places have shutters in your country. That would be the BEEEEEEEST method.
You can try blinds near drapes over them. You can try stained glass window with blinds or drapes over it.
You're greeting! :-)

yes they make blinds call "blackout." You can find them in cellular shades like mad of times. Try Blinds.com, I know they carry Prestige shades, and I know Prestige make them.
