Hi Ron,
There is a firm called Chips Away can easily sort that out for you.
However, if you want to do a basic job yourself, you need to get a product called Rubbing Compound (B&Q or Halfords), read the instructions, but use in small doses.
Oh one more thing Ron, I am not an expert on cars, I only know this, because I had a problem just like yours and I was advised to use this, it worked very well also.
