Anyone ever heard of these or used them? They sound interesting, and from a name like Gates, I can't imagine they are total junk, but at the same time, I have some trouble trusting a 'shrink wrap' hose clamp over a metal one...

My buddy uses them alot at his hotrod shop. They make for a very clean install. Problem is you have to be able to get the heat gun in all the way around and heat evenly. If you notice a leak, heat it some more.
Sooo... What if you can't get it heated right 100% around it? Will the 200ish degree coolant temp finish the job? One time use isn't that big a deal considering they don't cost a fortune, but maybe I'm just old school, but I question how it can hold better than a metal hose clamp.
The instruction hint at yes, but my buddy says no. He takes vehicles for a hard drive, then shuts them off so it'll heat sink and build as much pressure as possible. Then breaks out a heat gun and heats any leaks. When at full operating temp it's pretty easy to get the temp high enough to seal.
