Décor does a great job when I'm caulking my rig but if I'm only using a little at a time it seems to go bad and hardens up. It's expensive to buy. Is there some way to keep it fresh so that I can us...
I make a blob on the end of each tubes and let it cure. Next time I use the caulking tube it pulls off the end easily to be used again. I keep all of my caulking tubes wrapped in WM plastic sack and stored in a fridg in the garage. Lasts for years.
