Can clear and a gloss clear coat be mixed together or will it leave a film on the car?

Mixing a clear coat and a gloss clear coat is generally not recommended, as they may have different chemical properties and drying times. This can lead to improper adhesion and a potential film or uneven finish on the surface of the car. It's best to use one type of clear coat to ensure a uniform appearance and optimal performance. Always follow manufacturer guidelines for mixing and application.
