I use a product called Permalac. It is an exterior clear coat finish that protects wood, metal of all types. first clean the furniture using a good degreaser and scrub brush, rinse it off and let it dry. After it's dry you can either brush this stuff on or spray it on. I would use 2 coats, it drys to the touch in 5 minutes and is fully cured in an hour, so you don't have to wait all day for it to dry. www.permalac.com

Call a mud-jacker and weigh the costs. If the sub grade is secured and the elevation taken care of and it costs less than replacement.... then why not. if you are wanting something more decorative, you can always have an overlay installed on the existing surface.
