What? Radio shack sells plumbing paste? I thought this was an electronics  
place?

Of course then it will not work like it should! The plumbing paste seems  
to need much higher temperature to fully reflow, compared to the SMD  
paste. I suggest the OP gets some real SMD paste from a reputable supplier  
(that excludes Radio Shack) and it will work.
