I-putty engangeni manzi yezindonga zangaphakathi nezangaphandle: 1. Ukugcinwa kwamanzi okuhle kakhulu, okungandisa isikhathi sokwakha futhi kuthuthukise ukusebenza kahle komsebenzi. Ukuthambisa okuphezulu kwenza ukwakhiwa kube lula futhi kube bushelelezi. Kunikeza ukuthungwa okuhle nokulinganayo kwezindawo ze-putty ezibushelelezi. 2. Ukuthamba okuphezulu, okuvamile...Funda kabanzi»
