I use a the small 6cc dropper bottle for Deet and Bronners (from US Plastics; Lawson is selling them, too, I believe) - clear for the soap and a white one for the Deet. Both bottles would last quite a while.
I dehydrate t'paste and make dots and keep those in a tiny [craft-size] ziploc baggie, along with a pinch of baking soda to keep them from sticking to each other.
I usually wear long sleeves and a full-brimmed hat, along with shorts; I don't need too much. I currently keep my sunscreen in a 1oz bottle (also from US Plastics - with the dropper-insert hole drilled out a little). For long stretches above tree line, I'd take a few ounces (skin cancer runs in my family).
As far as AM - I carry tablets. ;) If you've MC's Backpacking Tips book, check out Tip #106 (how he uses AquaMira). It appears he repackages the two parts in 1oz(?) bottles and uses a 6cc or 10cc dropper bottle for the Mix.
