Try any australian made paint, Dulux(PPG), Hichem, Protec. Doubt you will get in 2pac unless somebody good colour matches for you

India Ivory(d07770) actually comes up as a fleet colour or a F fleet colour,maybe a special order for a company that seen the light and changed to holden. No sign of granite grey

 Paint stripper is slightly cheaper but a "Rip and Strip" disc is the way to go. Much less mess and safer than handling toxic chemicals, doesn't take any metal off. A 180mm disc for a 9" grinder is only about $20 each. 6 to 10 should do the whole car. A 100mm disc for a 4" grinder is about $14 but you would use 10 to 15 and a lot more time. Any Auto Paint supply shop would stock
