Are my control arms bad?

[C1ph3r]

I just dropped off my control arms at the sand blaster to get cleaned up. But before I go as far as powder coating them or painting them I was wondering if they are still good.

I know these pics aren't a lot to base it off of. But when I removed the control arm shafts, I found that the edges had been eaten into pretty bad.

you can see in the first pic a ribbon of metal. all 4 of them had this to some degree. but this is the worst one.
