I have some old Bang sent ( crawfish )in a spray can ( about 4 years old ), is it still ok to use? Or do you think it is no good and to throw it away? :-? :-? :-/ :-/ :-/ :-/

Should be fine to use.

As long as it wasn't in extreme heat I wouldn't hesitate to give it a try.

I would use it for sure.  I found one of my old boxes that had a bottle Dr. Juice in it from fifteen years ago.  I put some on a jig the other day and caught fish with it.  I don't know that the old sent helped but I know it didn't hurt.

Why not?

The molecules are probably not water soluable so they won't smell it anyway.

If it gives you more confidence then use it.

I put scent on everything I throw, even topwaters. Why?  Because.  It makes me feel more confident although the oil based scents cannot be noticed by the fish due to their not being water soluable.

And I smell great on the way home in the car, too!

Something just doesn't seem right to me about that arugument.  I know that Calorlina Lunker Sauce preaches about water soluability all the time in their advertisements but I don't see oil disolving in the air and I can sure smell it.  But maybe I am wrong.  Perhaps I should ask the Professor.
