First off the polish has hardly any smell which is weird. The polish is very finicky and likes to be layered over wet polish which is where I had issues. I layered it over several different colored polishes and they all cracked different and none of them resembled crocodile. I then had a stroke of genius and decided to try it on my swatch wheel with a regular old clear polish. I actually chose Wet n Wild clear nail protector and layered a super thin layer of Barry M. Croc Effects. I waited about 45 seconds to layer my Croc Effects over the clear and it worked pretty well. Fast forward to my nails where I used the same technique and it worked really well. I will have to try this polish again soon against a color that makes it pop more. It's definitely something new in the crackle/shatter family.
