I picked up my prop spinner from Joe at Buffex Metal Refinishing.He used belt sanders and ended up removing only about .004". He said that the spinner could be cleaned using Windex and that the spinner should be waxed and then have RainEx applied to it to protect the shine.
I received the replacement control cable bracket from Jason at Aerotronics.
One option to bring the left side skirt of the canopy is to install a replacement plastic block and move the hole inward. I drilled the screw holes in a new block.
