Product Review (submitted on July 27, 2011):
These dimples will require more than a "thin coat of filler" to cover. I purchased this for use with the countersunk all-steel aircraft-style rivets sold by Eastwood, intending to make aircraft wing type flush rivet lines, but found the shape and diameter of the mandrel is totally incorrect, resulting in an overly large and more or less flat bottomed depression - with no counterink taper to it! It's shape is simply NOT the same as a countersink. The dimple profiles were inconsistent too, with the base of many not laying parallel to the metal surface. A parallel jaw plier would be far more consistent..
