Wandering around with a bag of matchlight, looking for a match.
I would avoid food grade if possible, but with the $20 HF weed burner. I got coating out in two less than half-hour sessions. It comes off in sheets when it gets to the necessary temp. Worst part is the bottom perimeter, the heat tends to come right back at ya. I'll try to avoid it next time, but it was $20 for an otherwise very nice drum.
