Abstract
A test strip for measuring film build on a plastic piece includes a desired length of tape having an adhesive coating on an inner surface and a window. A paint strip of sufficient area to cover the window is secured to the tape by the adhesive. A backing formed from material easily peeled from the adhesive is removed when the tape is mounted on a piece prior to painting. After painting, the test strip is peeled away from the piece so that the paint strip can be separated from the tape, analyzed and stored.
