Slab-Renew?

Anybody use this stuff? I didn't want to link it because I don't want to promote it, and there may be more than one kind or brand. The claim is this stuff gets rid of scratches on slabs, and they offer testimonials. Does it replace reholdering, or is it smoke and mirrors?

Works best on PCGS slabs. Needs several applications however for NGC slabs.
Try it, I think you'll like it.
