Restoration
So, its been a year since I got this, i originally just used Hammerite Kurust to deal with the rust and, after damaging the spring taking it out, I used 12 gauge copper wire to make a new one, and used it on camping trips, but over-winter storage brought the rust back. Therefore a spent a couple of days dealing with the rust again, and repainting the tank with Simoniz vht paint, and the burner assemblies with the same. Then Simoniz acrylic fuel resistant lacquer. And im really pleased how it turned out...
HOWEVER, the problem now lies with the burner assemblies, although the paint goes upto 900°C, thats heat, and not fire. So the next step it to take them all back to bare metal and just keep them clean. And maybe figure out some kind of flame proof rust treatment.
The rust particles from the tank i managed to remove with blu-tac on a stick haha. But the rust "dust" came out with a couple of rinse and pour with the Aspen 4 fuel i got. Which then settles in the jug so I could filter it back into a different bottle.
