Removing pits and polishing glass fog lenses
So, my 95 355 had some pretty sand blasted looking fog lenses. Big thanks to Elliot for a few tips such as that these are glass lens.
Here if the process I used to get them close to new:
- Hold housing in a vise using rubber to protect - light grip pressure only
- DA Sander: 150, 220, 400, 600, 800, 1000, 3000, 5000 grits. Use 150 to sand the lens down to remove the pitting. Some pits are very deep and I decided to let a few of them remain as to not remove too much glass. After the pitting is gone, progressively work your way up in grits. I used a wet paper towel to wipe the lens and cool it all throughout the process.
- Polish with a glass polish disk, DA polisher (could be same sander) using 3M glass polish.
