Hi Everyone, I have several KDK ceiling fans and nearly all the blades have rust on the edges. Last summer, I took all the blades off, sanded them and repainted them with spray paint. But here they are rusting again. I'm probably going to take them off again, sand them again, this time prime them with the red anti-oxide paint and try again...but eventually, the sanding and painting are going to affect the blades. Does anyone know if you can buy replacement blades only? My fans work fine so I hate to have to replace the entire assembly.... Sorry, I searched the forums, but my searches turn up too many options that seem unrelated to be able to go through each one... Thanks! Judy
