I see alot of the pros i fish with spraying stuff on there lure and then the same stuff on there line and spool does anyone know of a product that you use on all three and for what purpose? and secondly does it work on what its suposed to do?

That's a new one on me.  I can't think of any reason for spraying attractant on the line/spool unless they feel that the oils used in the attractant slick up the line for better casting.  Seems like a waste to me, but then I don't profess to know everything

It's not really an attractant, it is a line conditioner that is supposed to keep your line from getting loopy and make it slide through the guides easier.  There are several different kinds and some may have an attractant in them, but that is not the real purpose.
