I found old paste sometimes dries out, beeing not properly "tacky" and not  
holding the components well.
Do never attempt to dilute it with alcohol or glycerine, you will  
experience a bad experience ;-9..
(All the painstakenly placed components jump of the board like popcorn  
when heated).
Maybe one day i find out what can dilute it without that problem....

If you paste is "wet" enough to work, and solders ok, there is no long  
term disadvantage to be expected.
