I've seen some nice dimples in cute girls and babies, but had not noticed dimples in pinblocks. I would appreciate being enlightened. Regarding sealing the block, I have thought of putting a couple coats of coating epoxy on a fitted, but not yet drilled pinblock, and then not drill completely through the block to slow moisture transmission in and out of the block. Obviously it would not have much effect in a consistent environment, but perhaps it would be of benefit in an environment where there are significant and frequent humidity fluctuations. Terry Farrell
