with a PolybondTuapphance-type finish.
It is so hard that asphalt-type cooler
undercoating will not stick to it.
Undercoat will break free and clog pump

treatments, or other additives in this
evaporative cooler. The use of any of
these products will void your
warrantyand may impair the life of
your evaporative cooler.

The hardness, adhesion and smoothnessof the
internal and external finishon your cooler makes
it extremelyunlikelythat scratches or chipping
