Before applying an expensive protective coating, you should clean the metal surface. Cleaned surfaces must meet agreed-upon profiles for acceptable coating effectiveness and service life. But surface profiles for measurement by conventional techniques are frequently inaccessible or impossible to secure. The Testex replica tape (Press -O- Film Replica Tape Kit) is used in conjunction with an analog or digital spring-loaded micrometer for acquiring surface profile measurements according to Method C in ASTM D4417. The micrometer thickness gage measures the average maximum peak to valley, surface profile ranges of the profiled testex tape.. Rub replica tape onto the abrasive blast cleaned surface forming a reverse replica of the peak-valley pattern in the steel. Then, quantify replica using a spring-loaded micrometer that determines the maximum peak-to-valley depth. Rolls of tape contain 50 pieces each.

Do not buy from this seller!!!
It’s not a testex and it is missing the thumb lever and you can hear pieces broken on the in side rattling around and it doesn’t work. Cheap knock off
