Application Notes
Thoroughly clean contact surface before use. Once P8500 has been applied, it cannot be removed and reused. Therefore, position P8500 carefully, assuring that it is in contact with all surfaces. If P8500 is misaligned, remove used unit, discard and repeat application with new unit. Test product for system compatibility as individual application conditions can impact results.
