Just want to share with all of you my successful experiment . buy a heat shrinking tube bigger in diameter than a regular analog . Cut it about 12 mm and placet on the bottom of your clearo or fluxo , with a lighter start heating the tube from about 1 inch distance . It will seal compleatle the bottom of your clearo/fluxo . Make sure you leave 3 or 4 mm at the end of it so it can close on the mettal peace when heated . It works , no more leaks . The heat tube I got it from my cruise ship where I work
but radio shak and ACE have it as well , few cents .
