There is an official body shop process (that you're not going to find anywhere legitimate because Tesla will sue the life out of anyone who releases such stuff), which, IMO, is mostly a guideline anyway. To do an actual decent job with something like a Tesla rear quarter you have to have the training and experience of working with them or similar things on other high end vehicles. There is no substitute for this.
If you don't know what you're doing and you try to do something like a Tesla rear quarter replacement... you might as well just take that money and set it on fire. Same end result... nothing accomplished except wasting money.
Even replacing bolt on stuff on the front of the car is trickier than people think. You've seen people complain about panel gaps on Teslas? If you don't know what you're doing there you'll end up with panel gaps you can stick your hand through. These cars are 50% shims. lol.
Apologies if I'm not totally supportive of a complete novice trying to take on any of this stuff. As someone who ends up getting contacted for help with nearly everything related to Tesla repair, I've seen far too many people who just have no clue what they're doing throwing a bunch of money at these things for no real reason. They don't know what they're doing and expect the ones who do to do a bunch to help them, generally scoffing at us when we don't want to do so for free or for pennies. In the end they either are left with half-*** repairs, an expensive paperweight, spend way more time and money on repairs than they should have (more than the vehicle is worth), or they just try to cut their losses and moved on. Out of dozens of people who I've dealt with fixing these cars, only a small few have managed to do anything successfully, and all of them had prior experience in one or more fields related to vehicle repair.
