Last year on this very day, I posted my Battle of the Top Coats experiment. It wasn't a pretty mani, but it was functional. I learned a lot about what to look for in a top coat and how to properly apply them to get optimal protection of your mani and to keep yourself from ruining the design your just worked so hard on.
Not all top coats are created equally, so if you're not thrilled with the one you've been using, try another one. Check out my comparison, don't be afraid to ask questions and tell me your thoughts. Hopefully you'll learn something useful too.
