I have found a chainsaw works like a charm.
Tom the tree hugger
Maybe for gum & carpet, however for pine sap on clear coat (automotive or FG) working with soft goo is easier to remove safely with a cutting agent.
It seems my neighbor's tree has dropped gobs of resin on my solar panels. Does anyone have any suggestions on removing the sticky stuff without damaging the panel. My first thought was a razor blade but I thought I would ask for help before doing anything to drastic.
Pine pitch plentiful in the ADK's. I use turtle wax bug and tar remover..spray on wipe off...leave on longer for the hardened ...paint and glass.
