I have had good success applying the varnish with a short bristle roller then immediately tipping it off with a foam brush. I do a 12" to 18" section at a time, tip it off, then move to the next section, overlapping the previous section by 2" to 6".

You need very good light and patience. Get down low and look at what you are doing. You can not go back to previous sections so it is important that you get it right the first time (at least on the last coat).
