If one has a slabbed coin with a few light scratches on the slab can anything be done to remove them? Any suggestions would be appreciated. I have read on line one or two methods I wouldn't want to attempt unless someone here has had success.
Yes you can go to wizard coin supply or an auto parts store and get plastic polish. Novus is the brand name. Its used for convertible plastic windows to remove sratches. Comes in 3 strengths
Hit the auto parts store.........they've got some cleaner there that's good for cleaning the plastic lenses on head lights.......that's the stuff you use on your holder.
All you can do is try some of the methods and if it doesn't work, the TPGs have re-holder services that are reasonable. Some slabs look like they've been through a war. Stuff gets bought, sold, sorted, and thrown around at coin shows too much. Sometimes the only good option is re-holder. Then I use plastic pages or sleeves in the boxes so they don't get scratched in my possession.
Try Turtle Wax headlight lens restorer. It works on headlight lens which are plastic so it should work on coin slabs. A few members have tried it and they recommend it.
I've used Flitz metal polish with good results. I tried it on a cracked slab that was sent in for re-holder
Paddy nailed it. Novus is a fantastic plastic/acrylic scratch remover and polish. Here's a link to their site for info including instructions. https://novuspolish.com/
I have used this product for years...on my Miata, boat plastic windows, coin slabs, any plastic with mild to heavy straches......I have no idea how the other products listed here work... however I have used this product for over 20 years! Never let me down to do the job to my satisfaction.
I used it for decades on acrylic aquariums that get scratched. And they ALL do. Ditto on the efficacy of the other products mentioned. I've no doubt some do work. I'm only speaking to what my experience has been.
When I had the boat...the plastic windows on the canvas takes a lot of abuse from sun, salt, and dirt...if you don't keep up on it ...it can get very costly replacing it....plus in a storm you want clear clean vision...that rain sheds quickly. My thoughts if it works don't change anything.....
WD-40 (and other light oils) don't actually polish out the scratches. What the oil does is fill the scratch and act like part of the plastic slab as far as light reflection/refraction is concerned. It's a good way to get a lightly-scratched slab ready for photos but I don't leave the oils on the slab after photography. BGW, WD-40 is not really an oil and it has tons of chemical additives. I use a pure mineral oil that is sold in the drug store for, ahem, personal use with regularity issues.
