Perhaps I'm the only one, but for me it was a BIG DISAPPOINTMENT and didn't function as others have posted.
Not bashing product here, just adding my experience. I never could tell what it did if anything, and the greying of the black plastic parts just continued worsening.
Finally got other products that worked fine.
O.K., I live in HOT Arizona..
The sun is very hard on paint and plastics in my area, but we don't have to worry about rust....
I tried all of the different products available, on my TJ. Where the fenders had faded to a light gray.
I experimented with TW Ice, Mequires, Aero-space 303, and Back to Black.
The best that I found was the Back to Black for the fenders. Two coats and really rub it in with a sponge, and then buff with a towel when dry. This restored my light gray fenders back to a deep satin finish Black.
On my 2013 JK, I use it on the fenders and bumpers, but have found that the Aero-space 303 works the best on the hard top.
It's important to follow the directions when applying both of these products.
It has now been over 6 months since I applied these products, and so far, they both look like I just applied them.
As for my Black paint, well the only polish that I have found, that doesn't leave smear marks behind, is Mothers Brazilian Carnuba wax cleaner. It gives you that deep wet high gloss appearance, and it's easy to apply!!!!!!!!
Since these products hold up under the harsh Arizona sun, then they should provide excellent protection, just about any place......
