After just using it as a blocking primer I must say it does sand out pretty well for an epoxy, but I do my heavy blocking with a spray poly. So as far as the epoxy being used as a heavy filling primer, that is not how i use it. When I spray it as a 1 to 1 mix, unreduced I am at a point where everything is already flat and straight so I can start blocking the epoxy with 220. Once you break through the first skin (that has a shine to it) it sands quite easy. And they do claim it has a very good resistance to chipping. Can't really back this claim as I just started as a blocking primer recently (not driven yet).
