Bob, all I can share is what I have done and observed. I have used it on chrome wheels several times before and they sheet water just like the paint did, so my assumption is that it works just as well.
Thanks for your reply Richy.
Since the onset, and by carefully reading all I can find about OG/OC, I too have assumed the same as you about the Opti-Coatings on Chrome wheels, as well as auto glass areas.
But:
I'm really anxious to learn how Coatings and some sealants that, in layman's terms will "etch" (bond) and become part and parcel of the vehicle's paint surfaces, can actually and effectively do the same on chrome and glass.
[Maybe in the case of glass, the Opti-Coatings (and perhaps other Coatings) mirror the new Hydrophobic Glass technologies in providing glass with a "film" in liquid form that cures. Of course, like most car care products, this 'new' glass technology also has 'ingredients/chemicals' that are proprietory.]
Can't even venture a guess about chrome, except:
I realize that no surface is completely impervious, or solid if you will, and has microscopic "pores" to differing degrees/sizes. Maybe that is the key to understanding how bonding, (whether it's co-valent or hydrogen, as once explained to me), of these Coatings, sealants, or even waxes can occur.
Then again, perhaps Coatings and some sealants may just "lay-on-top" of the Chrome and glass surfaces similar to the characteristics of some wax products; that is: Just bonding within and across the Coatings and sealants themselves, thus forming/providing a sacrificial barrier/protective matrix across the chrome/glass surfaces. Then again, perhaps not.
Therefore, I feel at this time that I need further info regarding my concerns of Coatings/sealants that are being applied to chrome/glass surfaces. Hopefully others will chime in with that info.
Again Richy, THANKS!....Your input on this matter, as well as many, many others, are always appreciated!
Bob
