Uniflex 255 vs. Interlux

On my first trailer, I used CPEX as an undercoat and Uniflex 255 as a finish coat. Uniflex 255 is an incredibly durable 2 part epoxy system. My problem is I can not get the smooth finish I want. It came out good by rolling it on and using a foam brush to drag it out... but I can not get it that last little bit to make it look really good... plus, it does stain (and it is white so it shows).
Anyway, I did some checking and some boat owners are using CPES to saturate the wood with a penetrating resin, then finishing it with Interlux.
After I get back from KY in a couple of weeks, I plan to start trailer no. 2, and will be faced with finishing it off at some point. I have a gravity feed spray gun and am thinking of using CPES first, then prime it and shoot it with Interlux.
So, am looking for feedback on the above. I figure white Interlux should last 4-5 years. It might chip easier from flying pebbles, but I think I can get a better finish with the Interlux over the Uniflex.
