Even dry paint weighs something. Just doing a quick search on the internet will reveal that a gallon of paint weighs between 9 and 11 pounds. A little further searching and I found a paint company with a FAQ that had a topic about the weight of dry paint in aircraft applications. They referred to a Material Safety Data Sheet to consult your paint's "percent weight solids". Their Example: Also i found this wiki article that claims that when removing the paint from early models of the Space Shuttle External Tank it dropped approximately 600 pounds. I know you can't believe everything you read on Wikipedia, but it stands as a fact that even dry paint does weigh something. Every little bit counts!
