OK, time to catch up here:
I haven't done any actual work on the stain since I bleached it. But, I did go back to Home Depot a few days ago and bought two brushes, a brass stripping brush and a steel wire brush. I also bought a can of Rust-Oleum Inverted Striping Paint and a container of Blacktop Crack Filler. Now, if none of this works, I'll start buying whatever else is suggested. I'll probably need to also buy a small, red pick-up truck to transfer all this stuff back to the house.
Oh, I also bought a lawn chair for gerntz.
