significantly extends the service life of tank coatings simply by illuminating insufficient film thickness wherever it occurs through the use of a portable ultraviolet flashlight. Pinholes, holidays and improper film thickness will contrast to the fluorescing coating. The result: pinholes as small as 0.25 mils can be identified and repaired before a tank is returned to service. Proper film thickness and uniform coverage can now be verified instantly.
