Spray it on your spool, then wait a few seconds for it to get down into the line. Next, cast a few times to sling the excess off. Finally, wipe down your reel's frame and handles as well as your rod's handle to keep from losing your grip on them. At the end of the day, I give each reel a little shot of Line Butter before I pull the cover over it and store it for next time, but I wouldn't recommend that unless you use reel covers, because this stuff is pretty oily, which will attract dust if left in the open.
