What is a decal Rocket League?
Decals are a customization option in Rocket League. Each vehicle has its own set of decals that can be unlocked in various ways. Decals record the number of saves performed while equipped. Typically, decals are obtained from crates, through trade-ins, and through player trading.
The Home and Away Version1 Rocket League decals can be purchased for the Octane, Fennec, and Dominus car bodies. Available now in the Rocket League Item Shop! Visit the Esports tab in the Item Shop to preview and purchase decals.
Generally speaking, the steps to install a decal are clean the application surface, remove decal backing, apply application solution (if there is one), position decal in the desired location, press firmly and use a squeegee to get rid of air bubbles.
