Driving in a sand storm? Sounds like the car was sandblasted pretty good. The car will never look or be the same after all that work. Also it does not sound like the quote includes paint matching.so with that metallic color the hood will most likely not match the rest of the car.

 

Any good paint shop can match any colour - metallic or not.

 

This new color paint requires a 3 step process to achieve the vin color. Just make sure the shop you select are capable of this process. Some Lexus colors are harder to match than others I've read. There are post here about paint matching and some are unsatisfied. In this case you may have to have the whole car repainted. Sorry this happened to your new car, bummer.

 

No, and I'm surprised your insurance company would go for that. Painting the entire car with an OEM quality job should cost less than $10,000. You may have to replace the headlights and windshield.
