paint na krwai....khali loha fit he...kharcha bi nahi ho ga....
sir use same paint....i dont remember but i think one TIN of silver color costs 3000 around (i forgot when i fully repainted my vitz a year ago)...you can buy paint your self....
the whole work in reasonable amount would be near 40 if the mech is sincere, if you get this work done from suzuki or toyota centre, then expect 2 lack minimum....
