Mike,
i have only one set of Indy's under my belt.
they were Tamiya's set for the Panther,
and i used Tamiya's extra thin cement (liquid).
it has held up ok so far.
Tenax is pretty strong in my experience,
so maybe the material of your links is somewhat resistant to it?
i have had some kits that are nearly impervious to the Tamiya cement
(like my Hasegawa Me163), so i think there may be some different 'formulas'
for styrene and different brands of liquid will work differently.
i have no hard data, but that is my suspicion.
if you have another liquid cement handy (MM, Pro-Weld, Tamiya)
give it a go.
good luck
