Neither heat from the hair dryer nor rubbing with acetone budged that residue or made a dent--or clean place-- in it. However, my arms are certainly getting a good workout a couple of hours a day. I still haven't located locally any of the stronger solvents fellow RVer's have suggested, but as soon as I get to Idaho Falls or Butte or Bozeman, I'm going shopping! In the meantime, it's back to "Scrub right, scrub left" while reading or watching television. I keep hoping I'll look up from what I'm doing and see that some of the mess is off the window.
