I've used a couple things Back to Blk and a Turtle wax product for plastic
I used the Back to Black on my jeep's fenders and that lasted all year so it is a good product

I just coat the top surface and leave the sides the faded black, adds a little contrast

I'm guessing to remove you have to remove the wipers also??

My fastening points were broken as well so the bolts really didn't secure tightly
I used over sized SS washers that catch the existing plastic but it's just a matter of time.
