Tried all the popular brands of diamond sprays / emulsions and this 1 micron emulsion worked amazingly well! I've never had a diamond paste, spray or emulsion work as quickly and produce such a clean sticky sharp edge. The container is on the small side however the emulsion seems to last a very long time between applications so in the end it works out the same as larger bottles that don't last as long. I recommend that you shake well and hold the nozzle right next to the strops and then spread as quickly and evenly as you can.
