It is painful haha, I had my front end first then went back for the rest of the car later on when I saw first hand how good it was and had one stone chip too many on the sides.
I didn’t pay that much, I’ve paid high 3’s but for a long term investment it’s worth it.
If all goes to plan i will be upgrading next year so not worth it for me . Totally makes sense having it done if its a long term car .
I'd go the same route as you if i ever get it done front end first then the rest .
