The original cook top on our Scamp
was pitted, rusty and ugly. I tried cleaning and polishing, but it was beyond that treatment. I then sanded it and painted it with high temperature automotive paint
Success was short lived. The high temp paint
didn't adhere well and burned off in some areas quite quickly.
I ended up buying and installing a used small yacht quality range which has held up very well.
I have also been eyeing those glass propane
cooktops in the home appliance stores. They could be re-jetted for propane
and certainly be easy to clean. If I had it to do again, I would certainly investigate installing one of these.
