FTF Sales in Florida.

[Yournamehere]

Does anyone know the rules of face to face sales in the State of Florida? I've looked online, and from what I gather, the seller and recipient of the firearm have to be at least 18 years of age, and the seller should not sell the firearm to someone that has a felony record or has any implication that they will use the gun in a crime. Is there any paperwork required or is it just cash for gun? Any information is greatly appreciated.
