| I occasionally take the handset covers off and put a smear of silicone grease on the magnets to slow down any corrosion. There has been stuff on the Inspiration list about this, some people use grease, some use clear nail varnish, but at the end of the day, an exposed magnet in a sea water environment will develop corrosion.
I would have thought that magnets captivated in the plastic sliders, a bit like the VR3 buttons, would be a more corrosion resistant solution - but AP have addressed this with the Vision electronics, by making the buttons a completely different design on the new handset. |
