The pinholes of metal goods are removed by pouring the mixture of 50-70 wt.% hydroxy propyl metacrylate and 5-25 wt.% lauryl acrylate as one functional vinyl moner and 0.5 wt.% triethylene diacrylate as multifunctional vinyl monomer into an autoclave having an inner revolving net body, pouring again 3-10 wt.% 5000-9000 m/w polyethylene oxide/polypropylene oxide copolymer, 0.05-0.2 wt.% silane coupling agent and 5 wt.% polmn. initiator and inhibitor of 0.95-1.05 specific gravity, putting metal goods into the net body, submerging the metal goods into mixture solution with revolving the net body, pulling out, resubmering, repulling out, and heat-hardening in a hardening tank.
