Powerhead Posted January 4, 2019 Share Posted January 4, 2019 Happy new year to everybody. It was about time I put batteries in my old robots to enable them to move a bit after some months, and I noticed that rust spots that I had cleaned some time ago with WD-40 have rusted again and even expanded somehow. Is there a way to treat and permanently stop the rust of expanding and ruining my toys?! :-( Link to comment Share on other sites More sharing options...
