So sorry if there is already a post on this. I searched and could not find anything. my Canvas is sticky and discolored im thinking tree sap as there was some on the body however the canvas cargo cover is sticky and discolored on the entire top. My top on the passenger compartment has nothing on it. Can anyone help me out here on whats going on. I have done some searches and some post on tent forums talk about the waterproofing causing this and others talk about tree sap also. anyone run into this and come up with a solution and what is causing it?
