The spray device includes a body having a reservoir. The method includes filling the reservoir with a first composition having a non-volatile silicone fluid, an antiperspirant active, an organoclay material, and at least one liquid activation enhancer having a Hansen Solubility Parameter for Hydrogen Bonding, δh between about 2 and about 6 and a light transmittance value greater than 90%. The method further includes filling the reservoir with a liquid fragrance material after the reservoir is filled with the first composition to form an antiperspirant composition, attaching a valve to the body; and filling the reservoir with a propellant, wherein the hand held spray device has a propellant concentration after filling from about 30% to about 90% by weight of the total fill of materials within the reservoir and the non-volatile silicone fluid has a concentration from about 30% to about 70% by weight of the antiperspirant composition. ## Claims ### Claim 1 A method of filling a hand held spray device comprising: providing a body having a reservoir comprising a total fill of materials;
