It is not recommended to use Polish Seal directly over LCN's effect polishes, such as Magnetic Polish, Crackle Polish, Croco Polish, and over decals or acrylic & One Stroke paints.  Polish Seal opens the surface slightly upon application and then sets up and forms a glossy finish while drying, so when you apply it over certain nail art applications it will actually remove or dissolve the nail art or effect polish design. To prevent your nail art from ruining just use a top coat product like Wet Look, Super Hardener or Diamond Power over your nail art, let everything dry thoroughly and then apply the Polish Seal. Polish Seal dries in a light unit or under a 60 watt light bulb in 5 minutes, providing a hard glossy finish which can extend wearing time of your manicure and nail art up to 10 days.
