Can you use a wet saw to cut laminate?

You can , but its kind of like using a sledgehammer to pound in a tack !

If I have inside corners or complex shapes to cut, I use a table saw with a veneer blade. -But generally, just scoring and snapping works well for me. To score, place a metal ruler on the line you want to cut and score it 2 times carefully, now turn it over and score once on that exact line. The sheet will now part as soon as bent, very easily. Some practice will get you exact cuts. -I use a carbide scoring tool made by Richards, available in Home Depot.
