Well, I got a new can about a month ago and it still lists propane as the propellant. The product itself, I'm sure, still contains oils which are flamable. About a year ago, some friends and I gathered at a park for a bit of a barbecue. Nobody brought any lighter fluid and it's darn hard to light the coals when all you have is a half a book of paper matches. I thought about the problem. Determined there was no way to solve it with my PST, that duct tape was of no use, but that WD40 was the perfect thing. I always keep a can in the car (with my car, a roll of duct tape and a can of WD40 are essential). I liberally sprayed the coals, then used a match to ignite the stream from the can, and set the whole thing a blaze.
Coals are ready!
