As far as being anal...YES...you have to be your own worse critic...if your not, the it'll pass attitude takes over and that's the difference between good and great.
Whenever I used to hire new employees, I told them that I could be the biggest jerk they ever worked for or the nicest guy they ever worked for...the nice thing was that they got to decide. Similar thing with paint and body, nobody at a car show says did you see that average paint job in the corner, they only talk about the really good ones and the really bad ones...and we get to decide what is said about our own work.
When I get vehicles to the state that your Camaro's at, I hate to give the customer the keys...It's like it's mine.
You may be right, more than 99.99% can do it...they just don't bother.
