First of all, extremely sorry for the loss! I know; it hurts! and hurts really bad (Have been in such a tragedy last year, so I know how it feels?)
You may visit Aurengzeb CNG Station, National market / ALLAH wali market, Satellite Town, Rawalpindi. On the CNG station, there is a paint shop. You can take your car there. The paint guy will fully see it and suggest the best possible solution, in reasonable price, and least affect on resale.
