For ppl who want the wind screen get buffed
The Guy didnt grind the screen with grinder or any other thing. He just spread the polish thats is easily available in bilal gunj, he simply applied the polish like we apply on car body after that he spread some amount of water any he polished the screen with rotor, its like a body polisher machine. It took almost 45 mins and he cleaned the screen, results was very much amazing as screen was shining like it should be.
I also recommend to get it buffed
