saw a white bonnie today that had a white "cover" about 8-10 inches wide that curved down on the sides on the top portion of the rear window. didnt get to close to it with traffic but it definetely looked cool and unique from what i saw. any one else ever see one of these ?? at first glance i thought " what kind of car is that ? " damn thats a bonnie ! wanted a closer look but it was'nt in the cards. ill be lookin out for it.

it could possibly be home made, kinda like the cheap ricers that tint the top portion of their windshileds to be the same color as the car, probably to simulate a "chop top" look

Yeah Ive seen it done... its like a windshield visor... it looks alright but it blocks your vision...
You could also be talking about painted rain guards... Painted rain guards is a kewl Idea... I have been contemplating doing this myself. Definatly a unique look... Ive never seen it done on a bonne before...IDEA IDEA
