Ask your local shop for some plugs. See if you can get them the right color for your skis or close to it. Stuff the pointy end in and hit it with a hammer, best to use an amber headed hammer. Then, with a one sided razor blade shave off the protruding portion of the plug with a back and forth, sawing motion. Keep your finners out of the way! No water or moisture will get in. They are in for good. Very tight.... ooooh soooo tight! Opps! sorry! Slap that dog with a rolled up newspaper!
