Don't throw out that rusty garden furniture. Restoring it can be a great weekend project. Use a wire brush or sandpaper to remove rust and flaky paint. Wash, dry, and then give it a good coat of metal primer. Choose a good outdoor metal paint and apply a couple of coats. Invest a little elbow grease and you've got something worth saving.
