It's not as easy as you make it look, especially for those of us who don't have much experience with torches. I'm trying to fix holes in 3" irrigation pipe and I watched your video several times. I'm getting my pipe too hot (my hole is now bigger) but can't seem to find the happy medium of temp. More tips, suggestions, etc. for beginners might help, instead of focusing on how "easy" it is. I'm sold on the product, but what more would you add to a video (or put in a new video) specifically directed at us newbies?
