I spray my bow every time I go into the woods, also keep a fresh earth disk in my case.

Mauser, I had the same set of strings and cables for 2 years.Each year spending about 30 days in the deer woods, this doesn't include the hog, turkey (obviously didn't spray for turkeys), 3d and other shooting. Never had any problems and my razortec still shoots like a dream. I don't think it causes any problems, but JMHO.
