as far as the products go you can get great results with the simplest stuff, the car you see above is just plain rusto, odorless minneral spirits, and 4 inch foam rollers from Lowes.

its really all in the prep work and technique, the smoother you get the surface to paint on the better it will look. If you take your time you eventually get it down to a science, some of the older fellas might be able to explain the actual process a bit better. Happy rolling, and welcome to the forum
