After reading this thread I to tried the ICE...
It did not blacken up the cladding as much as I would like, even after two applications. But to be fair, she's been an outside car since I bought her in 2001 (and neglected a bit) so the cladding is pretty bleached. I to figured EZ-Z's method out for myself and it works better. The ICE is less staticly charged than other products I have tried.

After Two Weeks:
The ICE has held its color better than anything else I have tied. We had a good thunder storm the other day and I noticed some light streaking on the nose where water runs off the sharp corners of the hood. Other than that no problem and the water does bead off it excellently.
