The price of the Egg-shell enamel would not be much more than the Black enamel we now use for springs and it would go considerably further. The spraying of the enamelneccessitates a proper fume cupboard and fan, as if this is not available the operator soon becomes upset by the spray. Many parts are, however, done more quickly and better by brush. hadb | ||
