I feel your pain. Ours is 40'. It's definitely not on my top 10 love to do list. I still hand polish it though. Usually takes me the good part of a day if I stay with it. Mequiars once a year or so, and Mary Moppins Advantage every now and then in between. As for washing, the CR Spotless has been a lifesaver, as it does what it says. Spot free rinse. I wash and rinse with the CR Spotless, and it drys without one spot. Before this, I used a squeegee, which still doesn't get all of it, and a chamois for the rest. The spotless water rinse was worth the steep price to cut the wash time in half.
