The above post is true, but you can buy their stuff from their website,
www.conklin.com.
Again, I rarely ever endorse anything like this, and I have NO stake in this company or anything. I only mentioned it because it seemed when I bought my Florida home, both my glass shower doors were awful, and nothing seemed to work except this stuff. Then it seemed like other folks down there had the same problem. Never had this problem up here in NY.
Please do not think I'm a dealer or benefit in this in any way. I don't.
Respectfully, Frank
