oh my god throw a hissy fit i know it cam be annoying to spend all that time masking off the windows and head lights tail lights.
Then you paint it and it all screws up i know how you feel i painted my skyline 3 times i got mad and just sprayed one heavy coat on the body of that enamel paint and it took a day to dry but oh my god it was so smooth but it did have a couple of runs but it was smooth

painting takes time and if you rush through it it won't come out good and you will get fustrated and then you might do something you will regret just take your time
