You need this, my man, I had the same issue and it fixed all the scraping: https://a.co/d/0eUiLkcO As for theft, get a blue tarp, grab 5-10 small yard waste branches with some leaves still stuck on them, cut very tiny holes and push the branches thru in several places so that at least 7-8 branches with some leaves are just protruding out of the tarp. Add a few more branches under the tarp so it gives it just seems like a tarp full of cut hedge branches. Strap it all down, you’re good to go.
