    Scratched lenses BAD
    WASH VERY GOOD

    Get the sanding scratches consistent with 1500 -
    Then water sand with 2000
    Then water sand with 3000 Trizac
    Then fine cut polish by hand
    Finally Swirl remover by hand

    That's a chore, done a couple, but every time you look at the gauges you get some real satisfaction with how good they look.

    If you think that plastic lenses are a chore...

    TRY POLISHING SOME DOOR GLASS SCRATCHES... .GRRRRRR

    With plastic lenses at least you feel like you make some progress after 2 hours.

    Cool. I wanted to reuse my gauge lenses but they were scratched in one area. I may try your technique.

    I did some a while back. I used my Dewalt buffer on low speed. Wet sanded with the grits mentioned. Mounted the Buffer in a vise and gently laid the lens against the wool pad. This was kind of tricky. I got tired of trying to hand polish. Finished with foam pad and some clear coat cleaner. Duz-all.

    IF you try to use plastic lens polish after sanding it will take forever... I used actual 3m or Meguires medium, fine, and swirl remover. It only took maybe 10 min per grit... 30 minutes Total to polish the whole thing to optically clear.


    IT took maybe 30 minutes to sand through 3 grits...I used a swirling motion to sand... until the scratches were gone... you don't want to sand just the scratches you may create a distortion.. .or more than is already there :rolleyes:
