Pneumacore said its patent-pending enhanced version of Simoniz’s Sealtite Life X-tend tire conditioner, Sentry, has fluorescing properties to enhance the detection of rim cracks, bead leaks, punctures or any other signs of air loss. Sentry is especially relevant for the mining and aggregate industries, according to Pneumacore Inc., and was developed specifically with low visibility environments in mind, such as underground mining and nighttime driving conditions. The company added Sentry works equally as well in daytime or aboveground environments.
