In the last two months, I have learned it is ludicrously easy to bring a driveshaft back to life, make it look brand new, and so nice you don't even want to install it. I initiated this pursuit as it's my goal for the underside of the car to look almost as nice as the...topside.
I wish I had a 'before' picture, but the driveshaft was crusty, crusty black. I started by taking my scraper and scraped all the junk off it. After this I took to it with brake cleaner which took everything off right down to the rusty metal.

On my rolling shop table, I made a convenient driveshaft workstation by resting it on jackstands. |
 |
After it had been cleaned with brake cleaner, I started sanding the rust off with a DA which quickly brought the metal back to looking brand new. |
 |
These are the original factory-applied stripes (white, green, red), used for color coding the driveshaft . As the car moves down the line it is accompanied by a build sheet. The line worker would grab the driveshaft dictated by the color code on the build sheet. Or so goes the lore that I have read. I took measurements for each of the strips so I could repaint them. Closer to the end of the shaft were two gray lines. |
 |
The driveshaft is completely sanded, looking brand new. Next I treated it with several coats of zinc phosphate to protect against corrosion and condition the metal. |
 |
...then remeasured out the stripes and taped them off. |
 |
All the stripes are taped off. |
 |
I repainted the stripes with regular old enamel model paint...basically because it was the only thing I had where I'd have all the colors, and figured it would have *some* durability. Two gray stripes at the end, then the three middle stripes. After the stripes were painted I clear coated the whole thing with several coats of cheapie rattle can Duplicolor Clear. |
 |
And the finished the product up close. I wasn't striving for perfection on the stripes since the originals were very sloppy. I also wasn't striving for exact color matching. As the final leg of the driveshaft restoration, I took it to my transmission rebuilder where he put a new yolk and u-joint on it, so I could have a fresh new yolk to slide into the freshly rebuilt transmission. |
Awesome work!
