I just switched this week, I hope to head to the range next week. I have done my Sig230, M&P Shield 9mm, Glock 30, Berretta 92....long guns next.
Basically everything in this thread is exactly how I understand it. You tube is awesome for how to vids. Once going with FL do not clean or use anything else as the FL will eat normal petroleum products away.
If you think about how it works it makes perfect sense.
