To get the very last drop of paint out of a one gallon can, try this tip from "Handyman" Tip Trader Section - Use a stir-stick to lock two paint cans together. The spring action of the handles will keep the cans braced against the stick, and gravity will allow the paint to flow from one can to the other. You can call your local waste management facility to find out how or if you can recycle the used can - they may have a drop off facility where they recycle paint cans and donate them to the Habitat for Humanity. It's worth the quick phone call to help our environment go even greener!
