Sharp Custom Coatings

This business powder coated my valve cover for my engine. Without my knowledge it was done incorrectly. The business sand blasted my Evo X valve cover that has bezels that are non removal therefore sand was trapped in the valve cover when I put it back on. My car started making horrible noises. The dealership now tells me there is an immense build up of sand in the engine and oil which caused extensive damage. Now I need an entirely new engine or to replace every single conponent in the engine. The valve cover is unusable as well. I even need a new turbo. Anything the oil touched is completely ruined. Now I have no car and a pretty hefty invoice because of this businesses incorrect practices. I have spoken with the business owner and he has refused to take any responsibility for what his business has done to my car. It is his job to know when he can sand blast and when he cannot.
