I am thinking about doing this before I get my car painted. I saw a black one today and it looked nice until i got up to it, and they just painted the tails black. Will just welding metal a similar shape to the tail lights in and bondoing over rough edges be good enough? And what type of welding would you suggest...someone said do tack welding for something or else the metal will warp. If you had it done @ a shop, how much did it cost?

Thanks
