Rage ultra is a very nice product but still needs a finishing putty or glaze.. like Metal Glaze. The talc and resins used are very fine and don't require you to reshape the panel. Just a super thin coat is all you'll need to fill pin holes and fine scratches in your filler.
Read the P sheet or technical data sheet for the products you're using. The high build will tell you grit ranges as well as the Evercoat products.
You can sand with too fine of a grit or too coarse. The manufacturers will be the best source of that information.
