I use the dry film from megauk.com. You apply it with a laminator and then uv expose the area you want to keep. A developing agent then removes the areas that were not exposed to uv ( pad areas ). The film is then cured in uv and an oven and does produce a great finish. 

I have experienced some 'blisters' in initial application but I think this is just down to a clean environment. 

I have added a picture in the album 'Dry Film Solder Resist Mask board' to show my results.
