Q:  How does this twin protection system (GulfCoat & AC Leak Freeze Nano) provide the kind of corrosion safeguard I can count on?
A:  Applying both RectorSeal products addresses the fundamental issue of corrosion from both inside
and outside the compressor. AC Leak Freeze Nano Pro is a high quality, non-polymer refrigerant
sealant that won’t react with moisture or air. It is the interior solution. GulfCoat stops the exterior
corrosion problems because it is moisture and corrosion resistant while providing UV protection.
It is the exterior solution.

Q:  Why is a protective coating for coils necessary?  Can't you just clean it?
A:  Cleaning coils is about heat transfer and energy. A dirty or corroded coil will reduce heat
transfer, resulting in more energy use and, ultimately, higher utility costs. Your customers will
notice. You’re offering extended protection. Just cleaning coils helps —momentarily— but a
protective coating keeps the coils cleaner when you’re not there. That’s why we wax floors for
longer-lasting protection. Applying GulfCoat to coils adds a long-lasting shield of protection.
