Yes, unless you put hardner in it and then it only took one lifetime!
Probably Duco (nitrocellulose) you were using which was replaced by Dulon (acrylic). Both needed to be buffed, so Duco may have been dropped because of its explosive properties. Didn't they originally use nitrocellulose for billard balls to replace ivory, until they exploded?
What can I say.

Tacking off with air?
I find it the other way around... they give too good a result... you can spot (vintage) cars and bikes that've been done in modern 2 pak paints... they look excessively glossly :S
VHT?
I understand what a tack cloth is, but I don't understand what you mean by tacking off with air? Did you mean blowing the excess crap off with air, and finishing up with a tack cloth?
And what the heck is a PVA sponge and where would you get one?
When you tack jobs off, you use a cloth in one hand and air blower in the other. Both at the same time otherwise you just move the dust from place to place.
PVA (polyvinyl alcohol) sponges are as rare as rocking horse shit here and even I struggle to find them. Paint suppliers either don't know about them or don't want to know about them. They want to sell tack cloth as selling 2-3 sponges a year to every auto-refinish shop will only make them friends, not money!

PGT-26 on this page should give some idea.
