   It takes a black lite to see the dye...

   Chances are that you won't find it on your own.

   I don't recommend it, but they make an AC sealer that you can buy with   
   your next AC refill...the sealer is in the same can as the R134...sooner   
   or later you're going to need some oil in the compressor. If you don't, it   
   may fail on you and then you'll really be in trouble.
