My genuine HD windshield on the Dyna started peeling after 15 yrs. I bought a big yellow foam pad for the drill, and some PlastiX polishing compound at O'reillys. It took about an hour to polish all of the coating off. Some areas seem to fall off, others are stubborn. I ended up with a looks like new clear windshield.
Oh yea, I put the windshield on towels on the workbench.
