Seth -
This is looking much better ! Great job !
There is only one thing that I see - you used the words "overtime" in a couple of places at least, and I believe that when used together as this, the definition = time worked after a normal work day.
Believe you are wanting to say that "over a period of time", etc..., so the words need to have a space between them.
For example, "over time, the wax protection on the vehicle deteriorated".
