Sanding with 80 grit, round tubing parts such as four link or sway bars.

I haven't tried sanding these parts yet, but I thought it would be smart to ask first. Everything probably has some mill scale on them and maybe even a touch of light surface rust. My first inclination was to take the DA to them and do the odd shaped parts by hand. They have plastic bushing already pressed in and I suspect that tape probably isn't going to stick well, when I go to prime them.

Anyway, does anyone have any tips for this job? Any help will be appreciated.

Roll bars are the most common call I get as to how to sand.
Like jimC said, it's fast and great.
Roll bars are usually done in the car, and sand at this point is not always wanted.
It's up to you, blast, da with 80 or hand sand with 180.
Depends on the part you are doing as to the best and easiest way.
 
There are tube belt sanders that work well on round tubing if you have access to all sides. Wouldn't work on a cage in a car.

Well, I guess it's time to bite the bullet and get to it, trying your suggestions and deciding if I need some hate music.

If it's a roll cage, more than a 10 point. Then yes hate music is definitely required. But turn that shit off once you start painting and throw on some classical! And take some ibuprofen before hand, to help with the next day.
 
lol. No roll cage. It's suspension parts made from round tubing and a few odd-shaped mounts and things. The tubular A arms will fit in my blast cabinet, but not the four-bar parts, so I will take them outside and give it to them. I need to figure out how to make sure I don't get grit in the ball joints which were pressed into place by the manufacturer.

I find that the thick premium duct tape works well for keeping media out of places. Gorilla duct tape is pretty good stuff. Stuff sticks really well to things.
 
Thanks Chris, I will give the tape a try. Do you think a single layer is enough, or should I make it multiple layers?

Two or more layers is what I usually do. I try to get whatever I'm trying to protect sealed then add more over that.
