I've used Paragon Paints for several machine rebuilds and I can say that I have achieved very good results because the paint is such good quality. Spraying, unless you have a good set-up is not only time consuming but can be very disappointing if you don't spray very often. My alternative method is to prepare well (just as you would for spraying), and to use the best quality brushes I can get hold of. Equally good, I use small fine foam rollers which give a finish very close to spraying (my spraying!) and do it quickly, no masking etc.
