Abstract
A method for testing a treated metal substrate toward its propensity to receive and adherently retain a finish coat such as paint or the like; the test is made before the finish coat is applied by applying a strip of adhesive to a specimen treated substrate, stripping the tape, and then comparing the amount of 'soil' pick-up versus an established standard; 'soil' includes any of the treating material picked up by the tape from the treated substrate.
