Days Gone allows you to personalize your motorcycle and it includes, among other things, special paints. On this page of the guide we explain how to unlock unique skins/paints and how to put a special pattern on the bike.
Special paints / custom skins are storyline rewards for completing some of the game's story missions. Information about unlocking a new coloring you will receive after completing the mission.
To apply a special custom skin (paint) visit a mechanic in one of the camps in the game world, for example, Manny from Copeland camp.
From the menu, select Paint and Decals.
Usually the game only displays some standard decals. Press the R2 button to switch to special Custom Accents. You can choose one of the available unique paints and put it on the bike for free.
