They are only good for washing you car and THATS IT! Just paid $40 to have my headlights restored but now it has more scratches on it than before. I asked the guy over to redo it 4 times and he finally said thats the best he can do. They only use one rough sand paper and no fine sanding to sand out the fine scratches. Sh*tty-est piece of so called "professional" work I've seen. NEVER AGAIN!
