Ive nearly gotten my 66 broken down and had parts sandblasted from time to time. Next step is getting the frame sent off to blast. I was planning to remove the rear axle and not have it blasted but planned to wirebrush and use my sander where I can to get it ready to paint. I assumed its a bad idea to have it blasted since its got moving parts that wont take to having sand around them and cause trouble.
Once I get the axle unbolted from the frame what is the best approach to getting it prepped for paint, and things to avoid? There is a vent that needs to get plugged up so nothing gets in or out as I have it removed and work with it.
A few years back I had removed the cover and replaced the gear oil and sealed it with RTV, but other than that Ive done nothing else to it.
