Removing stubborn scratches from slabs - the solution.

RussRuss Posts: 48,514 ✭✭✭
So, I get this group of coins in and some of the slabs have deep clusters of scratches. My 3M plastic polish isn't even making a dent. I went to Home Depot and bought a buffing kit that mounts in a drill. This kit has several sizes of cloth buffing wheels, and different colored sticks of stuff. Rub the white stick all over the area of the scratches and the scratches buffed out with the wheel. Then polish the plastic with a cotton cloth. Took a little bit of pressure, but it works!

  • yo can use the the plastic polish with the buffing wheel also. I paint cars for a living and I often use plastic polish on headlights and tail lights with a buffer.

    Do you have to buff in the buff?
    It is not exactly cheating, I prefer to consider it creative problem solving!!!

    He better not! I think those are some of my coins and I don't want them scarred for life image

    I've been told I tolerate fools poorly...that may explain things if I have a problem with you. Current ebay items - Nothing at the moment

    I have a world of scratched slabbs.
    Is there any risk of any of these compounds permeating the plastic and damaging a coin?

  • Once upon a long time ago I was an aircraft structural mechanic in the military and we used to polish scratches in aircraft canopies. Removing scratches is a breeze. We used similar kits called Micro Mesh kits.

    What was not a breeze was getting the scratch out without causing an optical distortion in the plastic. You had to work a small scratch over a large area to keep from causing visible distortions.

    Don't polish the edges.

    I believe it is well established that slabs are NOT airtight, but the risk of damage from a polishing compound is small.

    Like the creator, this method is flawed. You easily can distort the plastic, and ruin the slab. Put too much pressure on the drill and the slab will melt.

    Given that scratched slabs may not allow best representation of nice coins ( Not those where hairlines , dings or other defects are being hid by the poor slab surface), how many dealers polish the slabs before trying to photograph and/or sell them?
    If only a few then why?

    I would agree that was a dumass comment. The average home electric drill does not spin anywhere near the RPMs required to generate enough heat to 'melt' a hard plastic slab. Even distorting the plastic would be pretty unlikely.
