Loose Glasser Plastic Tube "Wrap" After a while these plastic tube wraps fail because they have stretched out a little bit and the original glue no longer holds. The quickest fix I have found is to wrap two bands of masking tape near the ends of the tube. Build up the tape until you can slide the tube over the wrap and it's snug. Then put some CA glue one the tape bands and slide the tube back into the correct position, using a slight twist when placing in the correct spot spreads the glue more evenly.
