Zandoval only uses a tube of glue once on the road then puts it away? How crazy is that? Those tubes will last months and months. Last summer I had a tube with me that had lasted for over a year. After getting a flat I scuffed up the hole on the inner tube, opened the tube and squeezed out...nothing. It was empty. They do last for months. Sometimes for months and months. Over the years I was able to save up to $2.00 by just keeping my old glue tubes forever. It only cost me about 3 hours of hassle when there was no glue after months and months and months. Keep your little glue tube new. What an idea. Thanks . How crazy? Crazy smart.
