A friend of mine has got one of those Steinel LCD guns, I
should of tried it before spending my money on that old and
used Leister hot air welder. The air pressure from a hot air
welder is a lot higher than a heat gun, so I'm not sure how
well it will work, but if you had successfully built your
tanks from it then I cannot see any major problem with using
a general purpose hot air gun. All the reducing nozzles for
hot air guns also have a side vent that can get annoying.
The side vent is probably there to prevent too much
restriction of air flow.
