I have a synthetic line winch on my Wrangler. When I installed it a couple years ago, I had purchased a cover with it. However, the bumper I'm using recesses the winch very low in the bumper. It was darn near impossible to get the cover around the winch and secure it properly. So over the last couple years, I've let the synthetic line be exposed to the elements here in Iowa. Hot summers and cold winters. My question is, do synthetic lines need to be covered from the elements? Some say yes and some say no. Curious about the thoughts on this subject here at OB. Thanks.
