    Concerning this product:

    2-3/4 x 27.5 yd PSA Paper 400 Grit

    Item #31377

    Is it wet/dry? It doesn’t say that it is, but I can’t imagine a 400 grit that isn’t.

    Also, does the ‘PSA’ stand for Paper Self Adhesive? Just curious about that one (I know that is it is self adhesive…just wondering what PSA stands for.)

    I need an economical 400 grit sandpaper that I can attach to my durablocks and wet sand with. In the past I’ve just wrapped 3m paper from the big-box store around the durablocks, but that’s not really very efficient….and it wears off your finger prints!
