Dennis,
More trouble up front, but less each time you use it; not a bad trade off. I was using it full strength. I put a little piece in a tart pan, hit with the heat gun, picked it up with a gloved hand and poured it on the end of the log. I had one "brilliant idea" that did not work at all. I put wax chips on the end of the log and hit them with heat. I never knew it was possible to check a log in 30 seconds.

A shortcut that did work okay was to use the heat gun on one end of a full bar of wax and rub it across the end of the log. You get into a rhythm - only a couple of seconds in the heat, one back and forth over the log, back in the heat, repeat, repeat. Highly inneficient; a lot of wax drips on the ground (I did it over a big scrap of cardboard) and you can only use the big pieces (but you can melt the leftover small ones later) and you end up putting it on really thick in some spots to get full coverage. But if you only have a couple of pieces and you need to get it done quick, it works.
I got two and a half gallons of AS in the group buy for under $20, so right now it is my favorite. I really like how convenient it is. I have a bunch of logs that I sealed and split for spindle blanks mostly. I have been going through the splits rounding them partly to speed drying and partly to get a better idea of what I have (just measuring the ends isn't always accurate in determining what diameter cylinder you will get). I also square the ends better if needed (usually at least one end has a bad slant) and turning the splits does rub the seal off the ends (except for the ones I used TB III on). So I seal them again before putting them away. I just shake my jug of AS up, take the lid off and wipe my finger across the inside of the screw top and then wipe that on the end of the blank. No fuss, no muss.
