Default Re: Magnesium, stopping corrosion and powder coating

Steve,
We do a lot of control yokes and never had a problem. We strip them with aluminum oxide, epoxy fill and sand any heavy pitting, dust off with compressed air and then off gas 1 hour at 425f. Usually spray them hot.
Several out there 4 yo and look like the day we did them..
The acetone may be your problem IMO
