(1) Cov txheej txheem ua kua roj vanish: ntxuav lub ntsej muag ntawm cov ntoo → polishing nrog cov ntawv xuab zeb → thov cov hmoov moisturizing → polishing sandpaper → tag nrho scraping lub putty, sanding nrog sandpaper → tag nrho scraping lub putty zaum ob, polishing nrog nplua sandpaper → painting roj xim → txhuam cov kua roj vanish → nrhiav xim, kho putty, polish nrog cov ntawv xuab zeb zoo → txhuam ob cov kua roj vanish, polish nrog cov ntawv xuab zeb zoo → txhuam peb cov kua roj vanish, polish → xuab zeb nrog dej xuab zeb kom ploj, siv quav ciab, polish.(2) Kev tsim kho cov txheej txheem ntawm cov xim sib xyaw xim: ua ntej ntxuav cov hmoov av ntawm lub hauv paus txheej, kho lub hauv paus txheej → smooth lub hauv paus txheej nrog sandpaper → pleev xim rau ntawm lub pob caus → puag thiab txhuam cov putty → siv cov roj qhuav → txhuam cov putty thoob plaws → polish → txhuam cov primer → cov primer qhuav thiab tawv → txhuam txheej txheej → kho lub putty kho → polish thiab ntxuav lub thib peb topcoat thiab siv lub thib ob txheej → polish → thib peb topcoat → polish thiab siv quav ciab.2. Kev tsim kho cov ntsiab lus ntawm kev tsim kho tshwj xeeb rau kev tshem cov roj thiab txhuam hniav Sib tsoo lub hauv paus txheej yog txheej txheem tseem ceeb rau txhuam cov kua roj vanish.Cov plua plav, roj thiab lwm yam impurities ntawm cov ntoo yuav tsum tau muab tshem tawm ua ntej.Lubricating roj hmoov kuj tseem yog txheej txheem tseem ceeb rau cov kua roj vanish.Thaum lub sij hawm tsim kho, siv paj rwb txhob lo lo ntxhuav dipped nyob rau hauv cov roj hmoov siv rau ntawm qhov chaw ntawm cov ntoo, rub nws rov qab thiab tawm nrog koj ob txhais tes, thiab rub cov roj hmoov rau hauv lub qhov muag tshuaj xyuas ntawm cov ntoo.
