I have been using edge and NPA

for years.

Quite simply both work for me quite well.
Npa 1 to 5 ratio, used with cool water.
Edge both spray

and dropper work well.

What i do is spray on cover scent first let it dry, at specific points on body. And then

apply with a dropper, on exactly the spot i have applied the cover scent.

Edge 2 to 3 drops, NPa 1 to 1.5 drops.



Also use nol product also ie soe, dr dodds stuff. Works well. cheers
