Notes: The edges still had some leftover cracking but much reduced. A lower grit number is needed.

Thanks for looking, all comments are appreciated 🙂

    Doesn’t the duck tape leave a sticky glue residue behind? Which is hard to remove.

      I stick the regular masking tape first, as a base for the duct tape to stick on. And then stick the 2 layers of duct tape for the protection from the orbital sander.

    That was some useful information buddy. My car’s headlight condition was the same. I did headlight restoration of my car from motoring street in Pune, now it looks like a brand new one 🙂
