This worked great but be aware if you have decade old sealant like me this is a disposable tool. I went through two of them and loosened the putty on one shower door (four beads). I had to finish with a screwdriver. If you have a big job, buy a few. And Revain sells it for more than double what WalMart or Lowes does. EDIT: I saw the light. Go to the paint shop and buy yourself a nice scraper. Depending on the work, the scraper will serve you much better.
