After the initial sanding step, I changed to a finer grit stick and started sanding out broader areas to smooth out some of the rougher areas. The key to success is to work slowly through a successive series of ever finer grits.

Here's the result after sanding all three windshields with an even finer grit sanding stick than was used in the previous step. As you continue to work, you'll see the transparency slowly start to return.

Additional sanding with the finest grit sanding stick I had available resulted in even greater transparency. Extra fine sanding sheets also work well at this stage. You may find you'll want to use several different tools throughout the project, sanding sticks, sanding sheets, etc., depending on the shape of the area you're working on.

After all the sanding is done, it's time to switch over to the Novus polishing system. Start with the No. 3 Heavy Scratch Remover, and following the instructions on the bottle, start polishing both surfaces.

As you continue to polish with the Novus No. 3 you'll notice a dramatic increase in the clarity of the piece.

Once you've gotten things pretty well smoothed out, switch to Novus No. 2 Fine Scratch Remover for the final polishing. Again, follow the bottle's instructions.

You can also use a fingernail buffing stick to do a final clean up fine scratches.

The last step is to do a final polishing with Novus No. 1 Plastic Clean & Shine.

And here's the finished product. All that sanding and buffing pays off!
