AlWhy on earth would I recommend WD-40 to solve a surface problem if I haven't used it many, many times myself with great success? Perhaps you missed the part about "wipe immediately". I own about 700 slabbed cards and have used WD-40 over and over to remove glue, marks and even a few minor scratches. I suppose if you left the stuff on there overnight it might eat into something, but that's why you have a clean wipe nearby to remove the stuff. My slabs clean up like new from PSA. I have never had a problem using WD-40...BUT, to each his own, I was just trying to pass on a technique that I've found to be very efficient in rejuvenating slabs.
