Hey guys, I have a few PCGS and NGC slabs with scratches in them. Recently I was restoring one of my headlights which was all scratched and yellow, and it got me thinking: what if I used the same technique on the slab. Has anyone tried this? If not, I may try various techniques and document them for the future. PS: I know TPGs offer reholdering services for about $12, but after shipping, handling fees, etc, it can add up. Also what if you want to keep your coin in a vintage/collectible holder?
I sure have with absolutely spectacular results. Used Turtle Wax Lens Clarifying Compound. A little compound and a lot of elbow grease. Only caution is that the stuff also removes the TPG hologram so don't let it get on the hologram.

Thank you guys! I ended up using an automotive polishing compound and it did a great job at removing the scratches!
With a polishing tool and the use of several steps of increasingly finer abrasive you should be able to polish out all but the deepest gouges, with excellent clarity. https://www.harborfreight.com/3-in-mini-polishing-and-buffing-kit-with-14-in-shank-4-pc-69335.html
I use a Meguiar's PlastX, a rag, and elbow grease. PCGS slabs are easier to polish than NGC. If you search the forum for "PlastX", you'll find several threads about polishing out scratches on slabs. I'd be careful with buffing and polishing tools, because they can melt the holder if you're not careful. Practice on slabs you don't care about first.
I used the meguiar's ultra finishing polish, but as a finishing polish, it does not have a very good cut. It got all the minor scratches out and left a nice finish though. Does plastX help with deeper scratches?
With enough rubbing, yes. If you have nasty gouges, you'd probably be better off with wet ultra-fine sandpaper first.
I use tooth paste to clean the headlight covers, don't know if it would work on the plastic slabs. You might try a magic eraser I know they take out scratches in counter tops. You can buy them in any grocery store.
