Jonathon. I am the owner of a large commercial painting company.
(www.painter911.com) I happened to run across your posting while doing
research for something else and I felt compelled to answer your
question.

First, there is not much of a difference between Sherwin-Williams and
Benjamin Moore. I spend over 100k a year with each of them. Both
companies have great products.

The Sherwin-Williams Duration paint is an excellent paint that I would
strongly recommend as long as you don't mind paying for it. I would
suggest still applying two coats even though it is not required.

***CAUTION***
Many painting house painters will not use the paint that they tell you
they are going to. Make sure to look for a reputable contractor at
www.PDCA.com. Also, insist that the painting contractor show you the
unopened can of paint that they will be using. Also, insist that they
leave any extra paint so that you may use it for touching up areas in
the future.

Also, insist that you see proof of workman's compensation insurance and
general liability insurance. If you do not and a worker is hurt at
your home, you WILL be held liable and you could lose your home.
***CAUTION***

I hope this post helped.
