Hmm, interesting to see the rusted hopper.
I have a Lil' Heater and have not seen any signs of rust. The Blaschak I was using in December was so wet I had to poke holes in the bottom of the bags. The coal actually glued together at the bottom of the hopper and I had to break it apart with a hammer.
The burning season only has 6 weeks to go, so I suggest waiting and then pull the hopper and apply several thin layers of primer and paint. Another suggestion is to find a sheet of Formica laminate and cut and glue the pieces to the inside of the hopper.
