About rubber coated mounting magnets:
These versatile neodymium magnets, protected in a rubber case, are water resistant and more resistant to damage that regular magnets, especially against metal strike. They are well suited to aquariums, construction sites and outdoor use. They also provide a greater degree of protection for surfaces that may require more care. These rubber coated magnets are often used to attach materials such as signs, bouquets of flowers or football jerseys to glass panes and panels. They are also used to suspend sun or privacy screens to windows or glass panels, and particularly to windows of cars and trucks, marine craft, motor homes, portable offices etc. Each fastening point will require two rubber coated magnets, one on each side of the panel. The magnets will not cling to the glass or plastic panel, but they will cling to each other through the material. Rectangular rubber coated magnets can also be used on varnished and painted surfaces. The high-quality Santoprene rubber prevents marks and scratches on these surfaces.
