I rigged up a better method of soaking the driveshaft without damaging the original paint stripes in the center. These stripes are very fragile and definitely not an oil-based paint. I think they are latex based as they are very sensitive to water. I pulled the soaking driveshaft out of the plastic gutter-based soaking rig as soon as I saw that it was affecting the stripes. This is what I came up with: A 4" wide PVC pipe with one end capped off, tied to my garage banister. The driveshaft fits perfectly inside with 1/4" to spare. I filled it with evaporust a little at a time and would lower the driveshaft down into the tube to see where the water line was. I settled on 1" below the stripes and let it soak for several hours on one end. Every hour or so I'd pull it out and wipe the rust residue off the surface. Once I was happy with one end, I flipped ends, readjusted the liquid level and did it again. It took very little evapoprust to do the process - less than one gallon, as the driveshaft takes up most of the space in the tube.
