Meguiars PlastX to get rid of slab scratches?

Meguiars PlastX to get rid of slab scratches? Does it work to get rid of light to moderate slab scratches? And if so, if someone could post best practices using it? Thanks

Yes, I use it and am happy with the results. Dab a drop directly on the slab and use a microfiber cloth to rub it in, using circular motion and a little elbow grease. Then use a dry part of cloth to polish it clean. That’s it!

Note: I’ve never tried it, but I understand it does not work on NGC plastic. Not sure about CACG.

Won't work on NGC, at least not easily. Works fine on PCGS.

It will work on NGC slabs, but takes more work/care in the process.

Thank you. Does that mean anything more than more time/bit more pressure?

Way more time. The NGC slabs are a much harder plastic.

I seem to create more scratches on NGC holders than I take off…….it doesn’t matter which product I use.

I actually use a damp, wet microfiber cloth, the kind you clean your sunglasses with. Very fine material. I use light pressure, circular motion, and gently polish, then polish with a dry cloth of the same type. Works great on PCGS slabs, not NGC.

Me, too. That's why I gave it up.

You would think that if the NGC slabs can be scratched then the scratches would come out.
I wonder about wet sanding using 4000 grit sandpaper or the Mr. Clean sponge which is a form of sandpaper for NGC slabs.

They are harder to scratch and therefore harder to polish. Polishing is, after all, just making fine scratches.

As jmlanzaf wrote the plastic is harder and it just takes more time and effort. I have also found that wet sanding with a 3000 grit sandpaper helps before you use any polishing compound like the Meguiars. My suggestion is to find an NGC slab that is one you are thinking about sending for reholder and use that for practice, worst case you send it for reholder anyway. PCGS slabs polish up easier for sure.

I just cleaned an NGC holder using Meguires and had no difficulty. Yes it took effort and multiple drops and polishing but it came out good. It wasn't scratched to bad though. I know some can be really hammered. I don't own any like that yet.

I have never taken any before and after pics, however, on the NGC forum a member there shared his experience and some before and after photos, as did a few other members.

I made a few threads on this with photos here and on the NGC forum. If you search a bit, you should be able to find them. Basically, depending on the scratch or gouge, you start with coarse sandpaper, proceed to fine sandpaper, and then polish it. Novus products worked a little better for me on the NGC slabs. They have a variety of grits of polish to work with. Also, a mechanical buffing wheel (on a drill) helps. NGC slabs are tough, but it can be done.

You should try to some time. You might surprise yourself.

I have only used it in one slab. It was heavily scratched so i needed more than just scratchX. I had to work fine grit sand paper from about 200 grit to maybe 2 or 3000.
Then used scratchX. I didn’t do a thorough enough job so some of the more severe scratches are still slightly visible but it’s a massive improvement from what it was before.
The scratchX is a very fine polish so if any of your scratches have any sort of depth, it’ll take you MANY hours of just polishing to get rid of them. You may need to go the sanding route.

I’ve used it on NGC. It does work.

One of things you can do to prevent scratches is use those clear plastic films they put on screens when they are new. Just cut out some circles and they self adhere and are easy to remove.

@PocketChange Let us know if you have success with NGC slabs. I’ve had little to no luck with them no matter what polish I’ve used.

Works great for PCGS slabs that are lightly scratched. If you have deep gouges you would need to use the technique that Bryce used in his thread. Then finish off with the Meguiars to polish out all the fine scratches left by the sandpaper.

As was mentioned, practice on a low value slab or a slab you plan to reholder anyways.

Good luck.
