According to Horizon 3 & Motorsport 6, tunes and paint jobs will grant in-game money to the owners of those tunes/paint jobs when someone downloading them, use them, selling the cars with them attach. It's need to be lock so another people can't edit it and steal the original owner works.
And, I remember someone successfully unlock the paint job in Horizon 3. That person already get ban. So, my suggestion would be try to ask the tuners for the infomation instead.
