I've never seen a magnet skinned, including countless kits, ARFs, jets and giant scale planes. I use the right size magnet for the job to begin with, so it doesn't need the 'skin' to help detachment. </span></div><div><span style="background-color: rgba(255, 255, 255, 0);">

The 'skin' is attached to the structure on the outside of the magnet, so there's no increase in attachment strength. Far from being an improved technique, it reduces the maximum hold of the magnet from the start and thus would seem counterproductive. </span></div><div><span style="background-color: rgba(255, 255, 255, 0); ">If you want help with removal, I would suggest starting with the right size magnet to begin with.

The fuselage foam for the metal screw was thin, so I cut a small area out and epoxied in a hard balsa block. I can screw the small wood screw out for magnet-to-metal security, or screw it in slightly an get rid of the 'clack' sound when the canopy seats and magnet hits metal. </span></div>
