I have always used a cover inside my garage and it seemed like it served me well. Lately, when I have taken the cover off my black viper, I see contact marks where it is stretched arond corners, etc. Being black, I am concerned it will start smudging the paint. I have a new duster and would need to use it every other day to keep the dust off the car before it gets too dusty to use the duster, otherwise I would need to wash it. I am wondering which is the least harm of both, either dusting it every other day and risking scratching it or covering and uncovering it and riscking scratching it.
