The crackle effect has become somewhat a phenomenon in the beauty world and the first time I used Rimmel Crack your colour Crazy top coat in 010 black graffiti I had high expectations. I've loved Rimmel nail polish before and the bottle is decorated with a zebra pattern so this was the effect I expected from the polish.
I first used it over a glittery gold Floozie nail polish (I don't know the name of the shade-it was from a Christmas gift set). I was quite disappointed to say the least. I did put a little too much on by accident at first so my nail went completely black. Too little though and no effect was there. The black blended more so with the gold rather than creating a top coat, even though I had left it a good half an hour between coats, creating a metallic black, which was good but not the desired effect.
I used the product again over the top of Topshop nails Ice crush (a clear glitter polish). The second time I used this I did prefer it to my previous use. As I had already applied the product I knew how much to use. However, the effect was not that of a zebra, it did create a crackle affect but it wasn't the most consistent product on nails as while one would have a great crackle, another would look mainly black with a few cracks in it. One advantage was that for a dark colour it did come off easily.
Verdict-Rimmel, I love you and your products but this is not the best one for me. My application was far from great I'll admit but this product was not what I expected. I will probably use it again (although I will be very careful with application. I'd stay stick to the Barry M crackle effect polish-I payed £4 for the Rimmel one but I'd rather pay a few quid more for the Barry M one.
