Great discussion everyone.
A) the haze created by alcohol is not visible when underwater, they all appear clear once underwater.
clear nail polish works well on loon, CCg, and my fav, tuffleye.
C) ccg and tuffleye need the appropriate lights, not sure about loon. With the proper lights they cure in 5-10 seconds, the wrong light just takes longer, it feels like forever but it is probably only 20-30-40 seconds.
D) the nail polish will yellow or brown over time. I know tuffleye sells a nail polish like visiting that doesn't, not sure about others.
Let me know if I can offer any other insights
