It's day 4 of having my hawk charged with Knox using the method I described in the forums.
On day two, I used hairspray on the base of the spikes to reinforce.
After that, no touch-ups.
From the pics, you can see what happened with using blue food coloring in the Knox mixture. It just made it look like I went swimming a lot. Next time, I will try half the water and double the food coloring.
All in all, not bad for lasting power, especially with the fact that it was a very watered down ratio by the time the food coloring was in it.
