Places where the laminate is about to chip off can be easily predicted
with a close inspection - you can see a bit uneven edge of a seam, with
tiny pieces of coating peeling off. If you slide your foot in a sock
over the seam, the sock will catch a piece of coating, and a tiny chip
may break lose (that's the chipping I mentioned in another post).

I was wondering if rubbing something like sealant into the seem may
make it smoother, and perevent further problems.

Sounds like a pretty poor quality-controlled product. If there are
protruding areas on the corners, as thin as they would have to be and as
brittle, there's no way you'll keep them from getting knocked off
eventually.

Your best chance to minimize the effect might be to take a 4-in-hand and
smooth the edges of each piece prior to laying it.
