I use automotive grade black silicone adhesive caulk, quite often, without issue.

 

Is black silicone really "black"? I'd rather go with something transparent then black.

 

Just got myself a tube of the silicone I mentioned on previous page. What is the best way to glue centercaps? Apply some silicone around the edge and then a bit more over remaining teeth?

P.S. I just realized I no longer can find any of the metal rings. Not sure where I placed them... perrrrfect...
