[Shop-talk] is there any such substance....

...that will temporarliy keep water from causing rust through?

Situation: I have a truck bed that appears to be Rhino lined. I do not 
know for sure it is has actually been Rhino lined: I put a 3 ton sears 
jack in the back of the track a couple weeks ago (got the jack and two 
heavy stands for $40 and the jack works! score). I turned it over so it 
would not roll around. I did this fairly gently and still got a small 
chunk of the coating loose.

Concern: I am getting rust through spots showing up here and there in 
the bed.

Question: Is there someting I put spray or brush onto the bed to keep 
this rust from gettting worse? Preferably a clear color....

I will pull the bed, strip it and then properly POR15 it but will not be 
able to until spring next year. I just need to keep it from getting 
worse in the meantime. This truck is and will be a driver until the snow 
(and salt) start to fly.

thanks!
