Gary,
2 issues here 
 
 1. you say , must be cleaned to new condition removing all marks!!! 
  how could anybody possibly guarrantee these results? I certainly wouldnt.
2 . you say . This is a new , approx six months old, with a few weeks wear!! 

 , but also say general traffic wear, surly a few weeks of service would not induce any noticible wear 
 
  Not that I am interested  

 , but was just a comment .
Geoff.
ps. also notice , big local company. Why big ?
