well it all depends wat do u want n how much u wanna spend on ur rims, its my elder bro car last year v faced the same situation, had 2 options either buff or repaint, trust me tooling is not a gud option, no doubt its cheap but it will decrease the strength of the rims plus the cuts make the surface luk v odd, buff costing 1000 rs/rim as well as bake paint. we opt 4 bake paint from a renowned rim/tyre shop (continental tyres) @ tariq road, they charged 1000rs/rim, scratched the rims with sand paper applied a thin base coat n then bake paint all rims, result is infront of u, no1 can say its remake even if u look closely.
