I have picked up a second hand TaylorMade Putter with a white finish on the top and back. As seems to be common there are a few chip marks on the white top which could catch the eye a little. I am toying with touching them up but don't want to make it worse with a bad match up. Has anyone repaired / touched up these types of putters? What did you use, was it effective, any tips? Am I better off just leaving it as it is?
