Hi there,  I have never used an anti-transpirant on cuttings, only on some
very large rhododendrons that had to be dug out and set aside for 3 weeks
while some construction was going on.  We sprayed them with "wilt-pruf", and
skidded them into the garage out of the sun keeping the rootballs moist.  I
lost one out of the 3 which I thought was great as I expected to lose all 3.
Can't really say the wilt-pruf did it, but it didn't hurt.
        Have you had any success rooting the above cuttings with the "old"
rooting hormone?  I was taught in school that it needs to be kept cool and
dry to remain effective.  I use it so fast that storage has never been a
problem for me.  But, I think 8 years is really pushing it.  If I were you,
if cuttings are not rooting in a reasonable length of time--I'd toss the old
stuff and try some fresh.  Good luck.  %^)
