3M Ultrathon Insect Repellent Lotion, SRL-12, 2-Ounces, 3 Pack

if I am wearing loose clothing, like loose pants, should I apply this even on my upper thighs and calves? or just at the ankles

Pic 1 shows n-diethyl-m-toluamide 31.58%. pic 2 shows deet 34.34% as the active ingredient. its advertised as a 3 pack. so which do you get?

About how many applications are per bottle? I'm going on a two week trip to Brazil with a total of 3 people.

what is the difference between the lotion and the cream?
