If you live near salt water or in very dusty or severe climates: use our Permanent Magnet Alternator Wind Turbine PMA Coating for extra protection on the PMA and anything else you need a high quality durable finish on.


*Optional Marine Finish:

Saltwater environments will cause the internal components to rust over time. Our marine varnish service includes disassembling the motor and coating the interior. As our sold-separately PMA Coating can only ship by ground service and is restricted in some countries, Missouri Wind and Solar is offering an add-on service to coat the internal components before shipping. Prolong the life of your Freedom PMG by protecting it from the effects of saltwater environments. Please allow additional handling time when choosing this service.
