I-bumper inokhuseleko, ihombisa kwaye iphucula iimpawu ze-aerodynamic zesithuthi kunye nezinye iinjongo, ngokwembono yokhuseleko, imoto inokudlala indima ye-buffer kwiingozi zokungqubana ngesantya esiphantsi, ikhusele umzimba wemoto yangaphambili neyangasemva, kwaye kwingozi yabahambi ngeenyawo inokudlala indima ethile ekukhuseleni abahambi ngeenyawo.

Emva kokuba isusiwe ukuze itshintshwe, i-plastic welding gun isetyenziselwa ukufudumeza nokuwelda ii-cracks ngasemva, kwaye intonga yeplastiki ye-welding iyafudunyezwa ngelixa ihamba kwii-cracks. I-sander yombane isetyenziselwa ukupolisha i-solder joint ephakamileyo kunye nokugudisa umphezulu wepeyinti owonakeleyo ngevili lokugaya lombane. Emva kwexesha lokuqala, i-putty yomiswa ngokupheleleyo emoyeni, kwaye isanti enobukhulu obahlukeneyo isetyenziselwa ukupolisha nokuyomisa, kwaye emva koko kufakwa i-chrome plating strip kwi-bumper.
