There are several companies that offer leak stopping elixirs. If the only problem is that the seals need softening, they may help. However, you never get that lucky. Most of the time there are worn bushings and other factors causing the leak. Some of the magic potions may indeed cause more problems than they solve. The main thing is to not let it run low on fluid and damage the pump. I recommend being proactive and flushing your power steering system every 30k miles. I have used the flush from BG Products with great success.
