Well, they got a tad worried when I got a lighter. Then I got the bottle of meths...
But not to worry. There is method in my madness.
The trick with sealing wax is to melt it over a burner. Using the stuff with a wick is not bad, but you get soot in the wax and it takes ages to drip the right amount.
The other trick is something to stop the seal sticking. One method is a moisture barrier (breath on it), but that was not anywhere near as effective as a small amount of bike oil (some stuff called WHite Lighting Eipc Ride light lube!). It leaves the seal a tad shiny.
