I was shocked to see the damage I had done to my rear bumper when I accidently backed into a stucco covered block wall - although I just "kissed it gently" the plastic was scatched - much like when you scrape your skin on concrete. I would call it more than a scratch. What do you suggest I do? Is this a repair job for a good body shop? Is this something I could do on my own?....my guess its for the pros.....Thanks...
