Thanks alot for your advice!
It is intimidating to make a huge flame for 1-2 seconds and then end clean using the inviso torch. I did hear that the inviso torch melts only if held too long or if the fuel is low the distance between the rubber tubing and flame is decreased; thus melting the tubing/striker. I'm still thinking lol. Hmm... Flash paper would add a quick spark to my production routines, but how would I end clean? I did look at the finger flasher (flint flasher) but i have no idea how to ditch it in a strolling/walk around type of environment. I assume I just reach for my pocket to do the ditch afterwards? Or what product would you recommend for ending clean?
