There is an actual "Tip Top" cement that looks like a hot glue stick, but its a darker yellow and a little stiffer. They are only about $1.00, and I think they carry them at G.I Joes, and that other place that rhymes with "Sky Mart". shave off little pieces, use a tooth pick to PACK, and I mean get as much as possible, into the tip, heat by holding next to, not over a heat source, until it begins to bubble out, then slide back onto rod. Back in business...
