Kev xuab zeb thiab ntxuav ntawm PLA qhov huv huv yog txheej nrog XTC thiab 3D kom cov xim tha xim xuab zeb thiab qhuav.
Txhawm rau kom kho daim ntawv xim av, nws raug nquahu kom xuab zeb luam tawm txij thaum pib los ua kom tiav kom tiv thaiv kev txhuam thiab kev tsim kho kom sov - thiab tsis txhob ua kom puas rau feem.

Nco ntsoov siv lub teeb kov kom tsis txhob ua kom puas cov ntsiab lus me lossis cuam tshuam qhov raug qhov ntev ntawm ib sab. Ceev faj thaum siv lub teeb sib dua kom tsis txhob ua kom cov ntsiab lus me me xws li cov chaw sib cuag, cov qauv kev txhawb nqa thiab lwm qhov chaw uas cuam tshuam los ntawm qhov tseeb qhov ntau ntawm koj cov ntu.

Thaum koj tau ua tiav sanding thiab tab tom nrhiav rau qhov kawg kov, koj tuaj yeem polish ib feem nrog yas polishing compound.
Koj tsuas xav tau li 600 grit rau kev pleev xim, tab sis yog tias koj xav tau daim iav - ua li cas qhov kawg tuaj yeem cuam tshuam koj lub siab ntev - koj tuaj yeem xau qhov siab rau 500 grit ua ntej polishing nws. Thaum koj lub siab raug mob zoo lawm, nws tuaj yeem tsim kho thiab txhuam nrog cov tshuaj aerosol primer. Qhov no ua kom ntseeg tau tias muaj kev tiv thaiv zoo tib yam thiab kom paub meej tias cov ntsiab lus ntawm cov ntawv luam tawm tsis tau muab zais ua ntej pib pleev xim.
