Leaking Power steering question

[disbo]

Hi Folks, I have a 94 with a 5 speed and Ive noticed that Im losing power steering fluid (I have to refill it about once every 3-4 weeks). I dont see any around the recepticle but I do see some from the steering rack.

Is this a common problem? Im not that excited about replacing the pump or the arm

Is there any product on the market that may help seal up this slow leak? I know there is some items like that for oil leaks.

Thanks Chris
