That is the cool thing Allen you are right on the money, just a little more time and you can fix most anything. And I am not saying to leave that curve in the window opening that way, most certainly, fix it.
It has always amazed me at how nice a home hobbyist's car will be! The funny thing is a lot of home hobbyists cars are actually better than the pros do, because they take the time to make it perfect where the pro knows that most people won't see the small imperfection. The home hobbyist hasn't learn that, thinking every flaw will be seen so they make it perfect.
Believe me, I became that perfectionist too. And I can't stress enough in my experience there is VERY little between the poor job and the outstanding job other than time spent on it. The guy who has the abilities to get in there and DO it, has the same abilities to do an outstanding job in most cases.
