Personally I use Duratec topcoat, as it's ability to fill voids is excellent and greatly reduces the amount of time you need to spend on sanding (making it almost redundant). But it isn't cheap.

I now have almost zero pinholes in my work if I have to make the part very thin the rest of my work is pinhole free. If you are using easypreg it should be flawless if you get it right and can repeat it exactly. (This is why I use a ramp and dwell controller). The material I use is now being sold by SHD Composites and it is called DF212. Its brilliant material if you get the cure schedule right. This seat back is straight out of the mould with nothing else done to it....
