Does neverdull have a shelf life? I had a can sitting around for maybe a year or so before I used it at all (never used a brand new can) and I just started to try and polish out the tips of my old (RB exhaust) and it's just not getting the job done. It gets most of it shiny and some of that gold-ish tarnish off, but still some of it's grey/black.

I know that english custom polish is supposed to be pretty good, and I'll probably end up ordering that, but I wanted to make sure that the neverdull doesn't lose effectiveness over time. I'm guessing not since it did seem to work for a few areas.

Instead of starting another thread later, should neverdull be safe with titanium? Replaced my RB with the HKS single and it has that titanium tip... I'm guessing it would be fine but didn't want to mess it up with an assumption.

 

Nevr dull is good stuff (used in the Navy to shine everything) But you gotta use a fine mesh scouring pads.
