Several years ago I used a 3M Stainless Steel Polish that had a lemony smell, and where I had been able to use my previous polish on the "black" and "painted" areas of the car (fascias, louvre, windshield reveals, etc), this new stuff after exposure to the sun turned those areas kind of yellow.
I then went back to using the Super Hi-Lite stuff and it cleaned up the yellow haze. After seeing the SS-Glo stuff here, I switched to that.
If this stuff from EcoLab (a big name here in the states) works on the painted/black areas, too, I'd be interested in seeing it in action at NEC this year.
