Not sure about skins anymore... I had all skins unlocked somehow for bike via opening hacked lootboxes from my inbox, also used mod to spawn specific items a long time ago if remember right to unlock backpacks skins and other skins (not sure if still works and is available somehow) Stopped playing the game because is s*** in terms of hacking now... Developers made an update at some point and "fixed all accounts" so all my stored energy drinks went to the inbox from chests (got 50 only while had 500-600 in chests before) and my coins balance went from 800600 to 5000 only and it wasn't able to modify it again after this update. If crates inbox hack still works or changing item in inbox from wood to bike paint item for example via GG you might be able to get some paints
