I just made a black railed board and the sand throughs flash like lightning on a black sky.
Today I had to go to a surf shop to buy grub screws (why aren’t they included when you buy the boxes???) and was inspecting boards and could not find any evidence of sand throughs, not even around the nose and tails (swallows). I had this feeling that they sprayed a clear coat. One board had black rails and that one for sure they sprayed the color, I’m thinking over the hot coat (it was matte black).
Does anyone know what tricks production shops use to hide sand throughs? Or are they really that good to have zero sand throughs? If they’re that good, how dey do dat?
