yeah great job,. it is not so much the application but the material, and you got a good grade of paint, dont get me wrong, the application is a great deal of the process but if you do have a couple of bad spots you can wet sand and buff it out with good paint, if it is crap paint then alot of the time it will actually change the tone of the color.
tell you friend that he did a great job and he should do it more.
