When I lived with my parents, I was in the basement, so I never worried about the sun damaging my stuff, but now every room at my place get lots of indirect sunlight. Does anyone cover their windows? Maybe keep your collection shelves covered? Will indirect sunlight damage plastic? My classics and MP/alternators are the only things I have displayed currently and for now, I have my Bookcase style shelves covered with black cloth to keep them basically in the dark all day. I'm curious to see what everyone else does to prevent sun damage.
