This?
The tubing looks nicer than the silicone glue that I often glob onto things. A wet finger can help to shape it.
Sugru is easier to use, but the glue is available everywhere.
EDIT: Yep, there is definitely something broken about links!
Hi Bill, the main thing with the tubing is to wet the steel as you’re sliding it. It requires some patience and dexterity to “work” it into place. I could see a vegetable oil working even better than water. Yes, I agree, the tubing is definitely going to create a nicer looking final result than the Sugru. The silicone tubing is what Co’s like MSR and Evernew use, so I went that route.
Another product would be something like Plasti Dip, but it’s only heat resistant to 200* whereas the tubing is heat resistant (they call it operating temperature) to 428*F.
