There have been some good posts on Archery Talk regarding heating up a bow string when waxing. I have been rubbing in the wax so hard that the heat would blister my finger. I saw a You Tube clip where a guy was using a hairdryer to melt the wax. Well, this might not be good. The material strings are made of are a plastic. High heat can deform the material. I am going to lightly wax with my fingers till warm when I get my Winners Choice.
