I would like to know if anyone has tried the oil "additive" Xado, ceramic metal

I plan to keep up on the regular maintence like I'm doing, but what I'm reading about "Xado", I wonder if it wouldn't be benificial to add this to the oil changes? I know it's a long shot that an additive would "chemically" remove some of the wear and tear from the cylinders and bearings, but would think that it wouldn't hurt to try?? I am using the "Lucas" oil treatment in an older 350 chevy engine (every 4th oil change) and it does help with "dry starts" seems to keep lubrication in the bearings, and I'm not seeing any "sludge" build up like I used to with the old STP that I used when I was a "youngster" and worked in a machine shop tearing engines down, and rebuilding them. Just figure that if this "Xado" would really "fill in" scraches and wear marks, it would be a good thing, and maybe think about distrbuting this in my area (agricultural area in Colorado) be nice to make some xtra $ but don't want to sell some junk stuff, so am looking for anyone who may have tried this stuff, I think it's fairly new to the market? Thanks for any info.
