What should I use to restore the black color on my convertible top. It looks like a dull black now. I do park it outside everyday since I live in an apt. Also, what can I use to get rid of the cloudiness on my rear plastic window? Why didn't Honda do the glass windows in the first place?

 

Try using 3M's 303 vinyl cleaner then use its 303 vinyl protectant for your top. Also, you might consider covering the car to better protect it from the sun.
As far as your rear window, Meguiars sells a plastic scratch remover (I think it is Meguiars #17) then use Plexus to coat the window.
Check out www.properautocare.com for the products.

 

aside from both of those "preferrred" products, I also use Porsche soft top conditioner "spray" It works really well. If you use it, be sure to cover the windows with large towels.

 

Vinylex from Lexol also works for the top. You can also use Meguiar's #10 to polish your rear window instead of Plexus.
