first you have knowledge about the materials, have many processes to make troug hole plating,        your bear in mind that materials are handled high toxic, cyanide is handled for platinum is very dangerous,        research about its handling, , on the other, only need a tray of plastic, a pair of Piz conductive and a battery of car is enough, look at your books for adolescents chemical process of electrolysis,        in terms of material you will use for platinum, the choice depends on the ending you want to give your circuit,         platinum can be done before or after coating paint, if the finish is an enamel, treatment is earlier, If with lacquer can be before or after, in addition choose whether platinized only be troug hole or via conductive coating
