Mixing epoxy with microballoons 50/50 works very good for the second coat. Less pinholes and easier sanding. I have tried thinning the epoxy with alcohol and altough some prefer it that way I actually like to use the epoxy as it is. I guess it's a preference, if thinned it's easier to apply epoxy with a wide brush much like painting though, but you can also end up with too much soak into the base material doing it like this so, or if not enough is applied it wont fully saturate the weave. It also affects the curing time and strenght of the epoxy, curing takes longer and strength is lowered.
