Hana ʻia nā nati rivet seal i ka hao, i kapa ʻia ʻo ke kila kalapona. Hoʻopili ʻia ka hao a huli ʻia paha, a ʻo kona kala maoli ka hopena o ka hana ʻana. No ka pale ʻana i ka pala, pono ia i ka electroplating. ʻAʻole pono ka hoʻopalapala ʻana i nā nati ponoʻī - kila kila. No ka hao, hoʻoholo ʻia ke kala o ka electroplating e ka mea kūʻai aku, ma muli o ko lākou kala makemake. Aia kekahi mau koi no ka paʻakai paʻakai. Pono kekahi mau kala electroplating i ka lōʻihi o ka paʻakai paʻakai, a ʻo nā mea ʻē aʻe e pulu i loko o kekahi mau hola. ʻO kekahi kumu ke manaʻo ka mea kūʻai aku e hoʻokuʻu aku i ka huahana. Pono ka ho'oku'u 'ia aku i ka uhi 'olu'olu, a ma ka 'āina kekahi, hana kekahi, akā 'a'ole ka hapa nui.
ʻO ka mea hoʻopalapala uila maʻamau i hoʻohana ʻia no ka ʻimi ʻana i nā nati ponoʻī ma ka mākeke, ʻo ia ka zinc polū ʻoluʻolu, no ka mea hiki iā ia ke pale i nā hoʻāʻo ʻana i ka paʻakai a hiki i 72 hola, a i ʻole ʻekolu lā. Hāʻawi kēia ʻano electroplating i kahi paʻakai paʻakai lōʻihi. ʻO ka nickel keʻokeʻo, no ka laʻana, ʻoi aku ka lōʻihi o ka paʻakai paʻakai paʻakai, maʻamau e ʻene i loko o kekahi mau hola, ʻaʻole ʻoi aku ma mua o 10 mau hola. Akā hiki ke ʻaila ʻia kekahi mau nickel keʻokeʻo, a ʻoi aku ka lōʻihi o ka manawa paʻakai o nā nati rivet i ʻaila ʻia.
