Gotta love some Tesla owners. You mention diy on some things and they become helpless people and would rather throw gobs of money at a company to do something that is very much possible diy. Poor kids, how do you manage?
I just did my car this week since we had 70+ degree weather. I used a 3m pro kit from ebay and did the partial front end. I would recommend not getting the hood emblem cut out because mine did not line up at all. They are sending me one without and I will cut it out myself. This is my 2nd time doing a full front bumper and very happy with the results. I had one small mistake near the top of the bumper where a very small finger just would not lay down 100%. Maybe the size of a pea at most. I was able to get it down but had to trim the film slightly. Its small and I will be the only one who notices it. The seams near the bottom front bumper between the two pieces were pretty challenging to stretch to.
Laying down PPF is not rocket science. You need the right ratio for your slip mix and also your stick mix. I used baby shampoo and distilled water, and 70% alcohol and distilled water. The kit will come with ratios. I added a little more shampoo to get it to slide around better. The hardest part is stretching since it's much more challenging than vinyl. You have to spray your stick solution on an area, and then stretch the film to that spot and adhere it. Fenders, headlights, and mirrors are all pretty easy. Hood will be easy when i get the new kit since it's flat. Bumper is a challenge. Lots of stretching and curves and there are a lot of painted surfaces.
I do recommend this

https://www.amazon.com/gp/product/B000BX4VXI/ref=ppx_yo_dt_b_asin_title_o01_s02?ie=UTF8&psc=1 Both were helpful. My kit same with a squeegee but this one I posted is better.
I will say this. Installing a kit is much easier than buying a roll of film and going at it on your own. That takes some very mad skills for the front bumper.
One more tip. Look at your car from all angles as you are squeegeeing. I did not and when I stood up there were about a dozen water bubbles I could not see from the position I was in on the bumper. Most were pretty small but a couple were medium and large. I have great led lighting in my garage but because I refused to look from all angles I could not see some of the bubbles. I went to walgreens and bought one hypodermic needle for $1. Smallest needle you can get. That removes the water and you cant see where you stuck the needle in since it will self heal the hole. You have about a 10 minute window to squeegee the water out. Once you are past that use the needle. Even the pros use them. I read about it from a ppf and tint forum.
Heres the important thing. My ppf job is not at a pro level and I didnt expect it to be. I wanted it to look good with some minor mistakes and protect the front end. I can peel it off in a year or two and do it again if needed. The whole kit was $280 which is 1/5th the cheapest quote I received. I saw the work of the cheapest guy I could find and he had some mistakes too. Better than me though. I also received quotes for a partial front end for almost $2,000. Hell no...
