^I didn't mean the product sucks. I was just saying it sucks in general that it can look brand new and in a few hundred miles it browns again.

I believe the problem you're having is that the clear coat keeps on changing color from the heat. On my 5zigens I ended up stripping the whole tip of everything, so it is bare metal and polished it from there. I wouldn't really recommend doing it. It was the only way I could get a mirror finish, so that was what I chose to do.

I'm wondering why no other venders have chimed in.. I think i will try the Never Dull product myself.. Although my Nurspec is pretty shiny I'm starting to see small dark spots on the muffler..

The small dark spots are probably tar.

and WD40 I heard is best to use for removing tar right?

Agreed... This past winter I found a small thin piece of metal that found its way in a muffler tip which had already began to rust. After I removed it, there was a rust stain which was left behind that couldn't be removed with soap and a wash mitt. I then used the Never Dull and with a little elbow grease I was able to remove the stain. My exhaust remains shiny longer than a week after I used Never Dull with no discoloration. It only gets dusty even after I apply polish.
