Kufenisha yensimbi eyehlisiwe, kufanele kuqashelwe ukuthi izixhumi zixega, azihlelekile, nokuthi kukhona yini ukusonteka; ngefenisha egoqekayo, kufanele kuqashelwe ukuthi izingxenye ezigoqayo ziyaguquguquka yini, kungakhathaliseki ukuthi amaphuzu okugoqa awonakele, kungakhathaliseki ukuthi ama-rivets agobile noma cha, ikakhulukazi amaphuzu okugoqa ezingxenyeni ezigcizelelwe kufanele afakwe ngokuqinile.

Ifenisha yezinkuni zensimbi iwuhlobo olusha lwefenisha, esebenzisa ukhuni njengento eyisisekelo yebhodi nensimbi njengohlaka lwamathambo. Ifenisha yensimbi neyokhuni ihlukaniswe yaba uhlobo olungaguquki, uhlobo lwe-disassembly kanye nohlobo lokugoqa. Ukwelashwa kwendawo yensimbi kuhlanganisa ukufafaza nge-electrostatic, ukufutha ngempushana yepulasitiki, i-nickel plating, i-chromium plating kanye nokulingisa igolide.

Ngaphezu kokunquma izinto okufanele zithengwe, ukuhlolwa okungaphezulu kuzokwenziwa ukuze imikhiqizo ithengwe. Hlola ukuthi i-electroplating igqamile futhi ibushelelezi, ukuthi akukho yini ukushisela endaweni yokushisela, ukuthi ingabe ifilimu kapende yemikhiqizo yokudweba i-electrostatic spray igcwele futhi ilinganayo, nokuthi ingabe kukhona ukugwebu; emikhiqizweni engaguquki, hlola ukuthi lukhona yini uphawu lokugqwala endaweni ehlangene yokushisela, nokuthi ifreyimu yensimbi imile futhi isikwele.

Kufenisha yensimbi eyehlisiwe, kufanele kuqashelwe ukuthi izixhumi zixega, azihlelekile, nokuthi kukhona yini ukusonteka; ngefenisha egoqekayo, kufanele kuqashelwe ukuthi izingxenye ezigoqayo ziyaguquguquka yini, kungakhathaliseki ukuthi amaphuzu okugoqa awonakele, kungakhathaliseki ukuthi ama-rivets agobile noma cha, ikakhulukazi amaphuzu okugoqa ezingxenyeni ezigcizelelwe kufanele afakwe ngokuqinile. Uma ifenisha ikhethiwe, azikho izinkinga ezicacile ezingxenyeni ezingenhla, ungayithenga ngokukhululeka.
