Selokhu kwangena ubusika, i-Petroleum Resin imakethe yasekhaya ye-petroleum resin iyonke iphinde yabhekana nobunye "ubusika obubandayo". Ngokusho kwabadayisi, ubuthakathaka be-Petroleum Resin kulo nyaka emakethe ye-petroleum resin bunzima kakhulu kunaseminyakeni edlule. Umthamo wokwenziwe nezingcaphuno zehle kakhulu uma kuqhathaniswa neminyaka edlule. Yize isimo sesithuthuke kancane, ukuthembela kwabadayisi be-Petroleum Resin emakethe akukenzi buthaka.
Ukuthambekela kwemakethe yamazwe omhlaba ye-petroleum resin bekunokuvilapha eminyakeni yamuva nje, i-Petroleum Resin ngokuqondile ngoba imakethe yasekhaya ye-petroleum resin ixhumene ngokungenakuhlukaniswa nokuthambekela kwamanani kawoyela aphesheya. Ngakho-ke, i-Petroleum Resin ukwehla kwemakethe kulobu busika akungenxa yezizathu zasekhaya kuphela. Yize abanye abadayisi bethi ukuthambekela kwemakethe yasekhaya kulo nyaka kunqanyuliwe kancane emakethe yamazwe omhlaba, iPetroleum Resin iyonke, imakethe yasekhaya yePetroleum Resin isahambisana namanani entengo kawoyela ongahluziwe.
Kafushane, i-Petroleum Resin "ubusika obubandayo" bubonke bemakethe ye-petroleum resin kulobu busika isaqinile isikhathi esithile ngenxa yamathonya ahlukahlukene aphesheya nawasekhaya, I-Petroleum Resin kanye nesidingo sasekhaya sasekhaya kungenzeka kusesesimweni esibuthakathaka. Kusenezinto eziningi ezingaqinisekile nezingazinzile endaweni yokuhweba yamazwe ngamazwe, i-Petroleum Resin ngakho-ke kunezici eziningi ezingaqinisekile emakethe ye-petroleum resin ezayo. Uma sibheka isidingo samanje semakethe yasekhaya, i-Petroleum Resin kulobu "busika obubandayo" ayithintwa yizici ezinkulu zemakethe. Ngaphansi kwezimo, i-Petroleum Resin imakethe isazokhombisa ukuhlanganiswa okubuthakathaka.
