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.
