Not all brands of CA is equal. Additives makes a large difference. There are a good 6 or so chemicals that can be used to create 'CA'.
Fumes from CA will cause allergy and flu like symptoms with exposure. it is not a question of if but a question of when. The only solution is to switch to odorless immediately. Odorless tends to be more expensive.
As for a good applicator try using the clear plastic bags the pen parts comes in, CA will not stick to that and it's a smooth surface.
